Nanodroplets versus Nanofibers Ion-Selective Optodes toward Biocompatible Sensors.

ABSTRACT: This work compared the performance of ion-selective optodes in different nanostructural formats: nanodroplets and nanofibers prepared from biocompatible materials using classical ionophores and ion exchangers. Nanodroplets tested contained minute amounts of plasticizer acetyl tributyl citrate stabilized with poly-(vinyl alcohol) and were suspended in the aqueous phase. It was shown that this system was not directly transferable to the nanofiber format; thus, nanofibers obtained from polycaprolactone were used as the support material. Both nanodroplets and nanofibers were used in Nile blue/Nile red-based systems operating as novel ion-selective sensor optical transducers, allowing sensors to be applied in unbuffered samples. As a model system, calcium sensors were prepared and tested. It wa
