Development of nano- and microdevices for the next generation of biotechnology, wearables and miniaturized instrumentation.

This is a short communication based on recent high-impact publications related to how various chemical materials and substrate modifications could be tuned for nano- and microdevices, where their application for high point-of-care bioanalysis and further applications in life science is discussed. Hence, they have allowed different high-impact research topics in a variety of fields, from the control of nanoscale to functional microarchitectures embedded in various support materials to obtain a device for a given application or use. Thus, their incorporation in standard instrumentation is shown, as well as in new optical setups to record different classical and non-classical light, signaling, and energy modes at a variety of wavelengths and energy levels.

Synthetic non-classical luminescence generation by enhanced silica nanophotonics based on nano-bio-FRET.

Fluorescent silica nanoparticles (NPs-(SiO-Fluo)) were synthesized based on the classical Störber method for cyanobacteria labelling. Modified mono-coloured SiO NPs with fluorescein (Fl) and rhodamine B (RhB) were obtained (NPs-(SiO-Fl) and NPs-(SiO-RhB)). Moreover, multi-coloured SiO NPs, the incorporation of both emitters (NPs-(SiO-RhB-Fl)), were tuned for optimal emissions and the biodetection of cyanobacteria.

Degradation of a series of fluorinated acrylates and methacrylates initiated by OH radicals at different temperatures.

Rate coefficients for the gas-phase reactions of OH radicals with a series of fluorinated acrylates and methacrylates: 2,2,2-trifluoroethylmethacrylate ( ), 1,1,1,3,3,3-hexafluoroisopropylacrylate ( ), 1,1,1,3,3,3-hexafluoroisopropylmethacrylate ( ), and 2,2,2-trifluoroethylacrylate ( ) have been measured for the first time as a function of temperature in the range 290-308 K. The kinetic data obtained were used to derive the following Arrhenius expressions (in units of cm per molecule per s): = (2.13 ± 0.

Designing electrochemical interfaces based on nanohybrids of avidin functionalized-carbon nanotubes and ruthenium nanoparticles as peroxidase-like nanozyme with supramolecular recognition properties for site-specific anchoring of biotinylated residues.

We are reporting an original supramolecular architecture based on a rationally designed new nanohybrid with enhanced peroxidase-like activity and site-specific biorecognition properties using avidin-functionalized multi-walled carbon nanotubes (MWCNTs-Av) and Ru nanoparticles (RuNPs). The nanohybrid-electrochemical interface was obtained by drop-coating of MWCNTs-Av dispersion at glassy carbon electrodes (GCE) followed by solvent evaporation and further electrodeposition of RuNPs (50 ppm RuCl for 15 s at -0.600 V).

Interaction of UO2 2+ with sodium dodecyl sulfate micelles: association of phenols to micelles through fluorescence quenching data.

Time-resolved laser-induced fluorescence (TRLIF) has been used to study the interaction of uranyl ion with sodium dodecyl sulfate (SDS) micelles in H(3)PO(4) 1 M. The titration curve consists of two curved regions with different slopes, one of them more pronounced at low concentration of SDS and the other, with a less pronounced positive slope at larger [SDS] until a plateau is reached. The fluorescence quenching of uranyl ion by para-substituted phenol compounds was studied by TRLIF and steady-state emission intensity measurements.
