In this communication luminescent bioconjugated human serum albumin nanostructures (HSA NPs) with tiny ultraluminescent gold core-shell silica nanoparticles (Au@SiO-Fl) were designed with enhanced bi-coloured luminescence properties. The HSA NPs were obtained from Human Serum Albumin free (HSA free) through the desolvation method, and Au@SiO-Fl, through modified Turkevich and Störber methods. In this manner, porous HSA Nanostructures of 150.

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.

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.
