Probing E/Z Isomerism Using Pillar[4]pyridinium/Gold Nanoparticle Ensembles and Their Photoresponsive Behavior.

ABSTRACT: Despite the fundamental importance and broad applicability of E/Z dicarboxylic acids, their discrimination remains challenging and greatly unexplored. Herein, we present a general approach for the recognition of E/Z diacids using supramolecular interactions coupled with plasmonic response. The method allows detecting both single isomers and their light-induced interconversion, which ultimately entails multiple reversible nanoparticle aggregations. Such a molecular recognition-coupled responsive nanoscale self-assembly resembles natural mechanisms and can be a versatile means of building artificial complexity.

Photoresponsive hydrogel networks using melanin nanoparticle photothermal sensitizers.

Project description:Photoreconfigurable and photodegradable polymeric networks have broad utility as functional biomaterials for many applications in medicine and biotechnology. The vast majority of these functional polymers are synthesized using chemical moieties that may be cytotoxic in vivo. Materials synthesized from these substituents also pose unknown risk upon implantation and thus will encounter significant regulatory challenges prior to use in vivo. This work describes a strategy to prepare photodegradable hydrogel networks that are composed of well-characterized synthetic polymers and natural melanin pigments found within the human body. Self-assembled networks of poly(l-lactide-co-glycolide)-poly(ethylene glycol) ABA triblock copolymers are doped with melanin nanoparticles to produce reconfigurable networks based on photothermal phase transitions. Self-assembled hydrogel networks with melanin nanoparticles exhibit a storage modulus ranging from 1.5 ± 0.6 kPa to 8.0 ± 7.5 kPa as measured by rheology. The rate of UV-induced photothermal heating was non-monotonic and varied as a function of melanin nanoparticle loading. A maximum steady state temperature increase of 20.5 ± 0.30 °C was measured. Experimental heating rates were in close agreement with predictions based on attenuation of light in melanins via photothermal absorption and Mie scattering. The implications of melanin nanoparticles on hydrogel network formation and light-induced disintegration were also characterized by rheology and dynamic light scattering. Taken together, this class of photoreconfigurable hydrogels represents a potential strategy for photodegradable polymers with increased likelihood for clinical translation.

Probing Nanoparticle-Cell Interaction Using Micro-Raman Spectroscopy: Silver and Gold Nanoparticle-Induced Stress Effects on Optically Trapped Live Red Blood Cells.

Project description:Advancements in the field of nanotechnology have resulted in the emergence of a large variety of engineered nanomaterials for innumerable applications. Despite the ubiquitous use of nanomaterials in daily life, concerns regarding the potential toxicity and safety of these materials have also been raised. There is a high demand for assessing the unwanted effects of both gold and silver nanoparticles, which is increasingly being used in biomedical applications. This paper deals with the study of stress due to silver and gold nanoparticles of varying size on red blood cells (RBCs) using Raman tweezers spectroscopy. RBCs were incubated with nanoparticles of size in the 10-100 nm range with the same concentrations, and micro-Raman spectra were recorded by optically trapping the nanoparticle-treated live RBCs. Spectral modifications implicating hemoglobin deoxygenation were observed in all nanoparticle-treated RBCs. One of the probable reason for the deoxygenation trend can be the adhesion of nanoparticles onto the cell surface causing imbalance in cell functioning. Moreover, the higher spectral variations observed for silver nanoparticles indicate that oxidative stress is involved in cell damage. These mechanisms lead to the modification in the hemoglobin structure because of changes in the pH of cytoplasm, which can be detected using Raman spectroscopy.

Single-molecule probing of amyloid nano-ensembles using the polymer nanoarray approach.

Project description:Soluble amyloid-beta (Aβ) oligomers are the prime causative agents of cognitive deficits during early stages of Alzheimer's disease (AD). The transient nature of the oligomers makes them difficult to characterize by traditional techniques, suggesting that advanced approaches are necessary. Previously developed fluorescence-based tethered approach for probing intermolecular interactions (TAPIN) and AFM-based single-molecule force spectroscopy are capable of probing dimers of Aβ peptides. In this paper, a novel polymer nanoarray approach to probe trimers and tetramers formed by the Aβ(14-23) segment of Aβ protein at the single-molecule level is applied. By using this approach combined with TAPIN and AFM force spectroscopy, the impact of pH on the assembly of these oligomers was characterized. Experimental results reveal that pH affects the oligomer assembly process. At neutral pH, trimers and tetramers assemble into structures with a similar stability, while at acidic conditions (pH 3.7), the oligomers adopt a set of structures with different lifetimes and strengths. Models for the assembly of Aβ(14-23) trimers and tetramers based on the results obtained is proposed.

Atomic force microscopy probing of receptor-nanoparticle interactions for riboflavin receptor targeted gold-dendrimer nanocomposites.

Project description:Riboflavin receptors are overexpressed in malignant cells from certain human breast and prostate cancers, and they constitute a group of potential surface markers important for cancer targeted delivery of therapeutic agents and imaging molecules. Here we report on the fabrication and atomic force microscopy (AFM) characterization of a core-shell nanocomposite consisting of a gold nanoparticle (AuNP) coated with riboflavin receptor-targeting poly(amido amine) dendrimer. We designed this nanocomposite for potential applications such as a cancer targeted imaging material based on its surface plasmon resonance properties conferred by AuNP. We employed AFM as a technique for probing the binding interaction between the nanocomposite and riboflavin binding protein (RfBP) in solution. AFM enabled precise measurement of the AuNP height distribution before (13.5 nm) and after chemisorption of riboflavin-conjugated dendrimer (AuNP-dendrimer; 20.5 nm). Binding of RfBP to the AuNP-dendrimer caused a height increase to 26.7 nm, which decreased to 22.8 nm when coincubated with riboflavin as a competitive ligand, supporting interaction of AuNP-dendrimer and its target protein. In summary, physical determination of size distribution by AFM imaging can serve as a quantitative approach to monitor and characterize the nanoscale interaction between a dendrimer-covered AuNP and target protein molecules in vitro.

Probing lipid membrane bending mechanics using gold nanorod tracking.

Project description:Lipid bilayer membranes undergo rapid bending undulations with wavelengths from tens of nanometers to tens of microns due to thermal fluctuations. Here, we probe such undulations and the membranes' mechanics by measuring the time-varying orientation of single gold nanorods (GNRs) adhered to the membrane, using high-speed dark field microscopy. In a lipid vesicle, such measurements allow the determination of the membrane's viscosity, bending rigidity, and tension as well as the friction coefficient for sliding of the monolayers over one another. The in-plane rotation of the GNR is hindered by undulations in a tension dependent manner, consistent with simulations. The motion of single GNRs adhered to the plasma membrane of living cultured cells similarly reveals the membrane's complex physics and coupling to the cell's actomyosin cortex.

Gold nanoparticle-based surface-enhanced Raman scattering for noninvasive molecular probing of embryonic stem cell differentiation.

Project description:This study reports the use of gold nanoparticle-based surface-enhanced Raman scattering (SERS) for probing the differentiation of mouse embryonic stem (mES) cells, including undifferentiated single cells, embryoid bodies (EBs), and terminally differentiated cardiomyocytes. Gold nanoparticles (GNPs) were successfully delivered into all 3 mES cell differentiation stages without affecting cell viability or proliferation. Transmission electron microscopy (TEM) confirmed the localization of GNPs inside the following cell organelles: mitochondria, secondary lysosome, and endoplasmic reticulum. Using bright- and dark-field imaging, the bright scattering of GNPs and nanoaggregates in all 3 ES cell differentiation stages could be visualized. EB (an early differentiation stage) and terminally differentiated cardiomyocytes both showed SERS peaks specific to metabolic activity in the mitochondria and to protein translation (amide I, amide II, and amide III peaks). These peaks have been rarely identified in undifferentiated single ES cells. Spatiotemporal changes observed in the SERS spectra from terminally differentiated cardiomyocyte tissues revealed local and dynamic molecular interactions as well as transformations during ES cell differentiation.

Structural isomerism in gold nanoparticles revealed by X-ray crystallography. [Corrected].

Project description:Revealing structural isomerism in nanoparticles using single-crystal X-ray crystallography remains a largely unresolved task, although it has been theoretically predicted with some experimental clues. Here we report a pair of structural isomers, Au38T and Au38Q, as evidenced using electrospray ionization mass spectrometry, X-ray photoelectron spectroscopy, thermogravimetric analysis and indisputable single-crystal X-ray crystallography. The two isomers show different optical and catalytic properties, and differences in stability. In addition, the less stable Au38T can be irreversibly transformed to the more stable Au38Q at 50 °C in toluene. This work may represent an important advance in revealing structural isomerism at the nanoscale.

Gene Expression in Gold Nanoparticle Oligonucleotide Complexes treated Primary Immune Cells

Project description:Gold nanoparticle (AuâNP) oligonucleotide complexes hold considerable promise as an approach for manipulating intracellular gene regulation. We show that the uptake and intracellular fate of AuâNP oligonucleotide complexes is associated with endocytosis and signal transduction. A transcriptomeâwide functional analysis of gene expression implicated multiple signaling pathways specific for AuâNP oligonucleotide complexes. In primary immune cells, the complexes trigger the expression of proâinflammatory nonâchemotactic cytokines rather than the many IFNâstimulated genes critical for induction of the immune response to a microbial challenge. Concordant with these changes, exposure to AuâNP oligonucleotide complexes is also accompanied by marked activation of immune cells. This distinct gene expression profile is not replicated in the lineageârestricted 293T cell line. These findings provide insight into the functional significance of the recruitment of AuâNP oligonucleotide complexes to endocytic structures and highlight the need to study the systems effects of nanomaterials in a biologically relevant model. We investigated the effect of AuâNP antisense EGFP oligonucleotide complexes on the transcriptome by expression profiling of 293T cells under four conditions and PBMCs under six conditions plus HIV infection with the Affymetrix U133 Plus 2.0 microarray. To control for experimental variability, three of the six PBMC conditions (24â and 48âhours after AuâNP oligonucleotide complex treatment, and the negative control) were assayed independently a second time (biological replicates) so that 13 microarrays were hybridized in total. A different batch of AuâNP oligonucleotide complexes was used in the generation of the four 293T and three replicate PBMC samples, and the microarrays for these samples were processed separately.

Colorimetric bacteria sensing of Pseudomonas aeruginosa using gold nanoparticle probes.

Project description:BackgroundDue to the advantages of molecular methods over biochemical methods, the use of molecular methods for diagnosing nosocomial infections such as Pseudomonas can be an appropriate and rapid way to choose the right diagnosis and treatment of infection and prevent further complications caused by the infection. The present article provides a description of the development of a nanoparticle-based detection technique for sensitive and specific deoxyribonucleic acid-based diagnostic of Pseudomonas aeruginosa. Specific thiolated oligonucleotide probes for one of the hypervariable regions of the 16S rDNA gene were designed and applied for colorimetric detection of the bacteria.ResultsThe results of gold nanoprobe-nucleic sequence amplification indicated the probe attached to gold nanoparticles in the presence of the target deoxyribonucleic acid. It caused aggregation of gold nanoparticles in the form of connected networks resulting in color change and indicating the presence of the target molecule in the sample, which could be observed by the naked eye. In addition, the wavelength of gold nanoparticles changed from 524 to 558 nm. Multiplex polymerase chain reactions were performed using four specific genes of Pseudomonas aeruginosa (oprL, oprI, toxA, and 16S rDNA). The sensitivity and specificity of the two techniques were assessed. According to the observations, the specificity of both techniques was 100%, and the sensitivity was 0.5 ng/μL and 0.01 ng/μL of genomic deoxyribonucleic acid for multiplex polymerase chain reaction and colorimetric assay, respectively.ConclusionsThe sensitivity of colorimetric detection was about 50 times higher than the polymerase chain reaction using the 16SrDNA gene. The results of our study proved to be highly specific with potential use for early detection of Pseudomonas aeruginosa.
