Selective organ deposition of nanoparticles directed by metal–organic network coatings_2

ABSTRACT: Despite significant advances in nanoengineering, developing a universal nanoparticle engineering strategy that enables tailored nanoparticle organ deposition post intravenous administration remains challenging. Here, we report a simple and modular strategy mediated by metal–organic network coatings composed of polyethylene glycol (PEG), proteins, phenolic ligands, and metal ions. The versatile binding affinity of phenolic ligands facilitates the formation of coatings on diverse nanoparticle platforms, including quantum dots, lipid, polymeric, inorganic, and metal–organic nanoparticles. The organ deposition selectivity of these coated nanoparticles is readily directed towards the kidney, lung, heart, and brain by varying the coating composition. Mechanistic studies reveal that the combined effect of PEG, phenolic ligands, and metal ions on the surface properties governs the overall biodistribution of the coated nanoparticles, while the protein component contributes to the coating integrity. This work provides a generalizable approach for developing an organ-targeting nanotechnology, with the potential to advance nanoparticle-mediated treatments and theranostics.

The effect of ZnO nanoparticles on gene expression patterns in Daphnia magna

Project description:There is still a lot of contradiction on whether metal ions are solely responsible for the observed the toxicity of ZnO and CuO nanoparticles to aquatic species. While most tests have studied nanoparticle effects at organismal levels (e.g. mortality, reproduction), effects at suborganismal levels may clarify the role of metal ions, nanoparticles and nanoparticle aggregates. In this study, the effect of ZnO, CuO nanoparticles and zinc, copper salts was tested on the gene expression levels in Daphnia magna. D. magna was exposed during 96 hours to 10% immobilization concentrations of all chemicals, after which daphnids were sampled for a differential gene expression analysis using microarray. When comparing the nanoparticle exposed daphnids (ZnO or CuO) to the metal salt exposed daphnids (zinc or copper salt), the microarray results showed no significantly differentially expressed genes. These results indicate that the toxicity of the tested ZnO and CuO nanoparticles to D. magna caused is solely caused by toxic metal ions. 4 replicate exposures of ZnO nanoparticles, ZnCl2, Blank (for Zn); 4 replicate exposures of CuO nanoparticles, CuCl2.2H2O, Blank (for Cu); Individual reference design with swapped dyes for zinc (e.g. ZnO-REFZn; REFZn-bl) and copper exposure (e.g. CuO-REFCu; REFCu-bl); Zinc reference sample is a mixture of equal aliquots of ZnO nanoparticle, ZnCl2 and blank; Copper reference sample is a mixture of equal aliquots of CuO nanoparticle, CuCl2.2H2O and blank

RNAseq of human epithelial lung carcinoma cell line A549 exposed to ceria, silver or zinc ions, micron-sized particles or nanoparticles

Project description:The toxicity of silver and zinc oxide nanoparticles is hypothesised to be mediated by dissolved metal ions and cerium dioxide nanoparticles (CeO2 NPs) are hypothesised to induce toxicity specifically by oxidative stress dependant on their surface redox state. To test these hypotheses, RNAseq was applied to characterise the molecular responses of cells to metal nanoparticle and metal ion exposures. The human epithelial lung carcinoma cell line A549 was exposed to different CeO2 NPs with different surface charges, micron-sized and nano-sized silver particles and silver ions, micron-sized and nano-sized zinc oxide particles and zinc ions, or control conditions, for 1 hour, 6 hours and 24 hours. Concentrations were the lower of either EC20 or 128 micrograms/mL. Transcriptional responses were characterised by RNAseq transcriptomics using an Illumina HiSeq2500 .

Deep Plasma Proteome Profiling by Modulating Single Nanoparticle Protein Corona with Small Molecules

Project description:The protein corona, a dynamic biomolecular layer that forms on nanoparticle (NP) surfaces upon exposure to biological fluids is emerging as a valuable diagnostic tool for improving plasma proteome coverage analyzed by liquid chromatography-mass spectrometry (LC-MS/MS). Here, we show that spiking phosphatidylcholine into plasma can induce diverse protein corona patterns on otherwise identical NPs, significantly enhancing the depth of plasma proteome profiling. This significant achievement is made utilizing only a single NP type and one small molecule to analyze a single plasma sample, setting a new standard in proteomic depth of the plasma sample. Given the critical role of plasma proteomics in biomarker discovery and disease monitoring, we anticipate widespread adoption of this methodology for identification and clinical translation of proteomic biomarkers into FDA approved diagnostics.

High-throughput plasma/serum proteomics by coupling nanoparticle protein corona-based sample preparation and capillary zone electrophoresis-tandem mass spectrometry

Project description:A high-throughput workflow for bottom-up proteomics (BUP) of human plasma using capillary zone electrophoresis-tandem mass spectrometry (CZE-MS/MS) and nanoparticle protein corona-assisted sample preparation is presented. The streamlined approach enabled the identification and quantification of hundreds of proteins from plasma/serum samples in 3.5 hours from sample to data. Nanoparticles with varied physiochemical properties studied in this work captured different pools of the plasma/serum proteome in the protein coronas, and the protein corona-based sample preparation approach enabled the measurement of low-abundance proteins compared to the approach without nanoparticles. Applying this high-throughput workflow to serum samples of a mouse NUT carcinoma (NC) cancer model allowed the determination of differentially expressed serum proteins between NC bearing mice and healthy controls. By comparing our quantitative proteomics data with published transcriptomics data, we revealed a handful of potential serum protein biomarkers of NC cancer (e.g., secreted phosphoprotein 1, Spp1). We expect this high-throughput workflow, with additional improvement in the speed of the mass spectrometer, will be useful for advancing the discovery of new protein biomarkers of diseases (e.g., cancer) using plasma/serum samples valuable for liquid biopsy applications.

Predicting the Protein Corona on Nanoparticles Using Random Forest Models with Nanoparticle, Protein, and Experimental Features

Project description:We describe the predicted composition and abundance of the protein corona as a function of protein, nanoparticle, and experimental features that serve as the input dataset in which our Random Forest Regression (RFR) and Random Forest Classifier (RFC) models were trained on. Predictions were made using a supervised learning model, which was evaluated on an unseen test split of the data.
