We report on the realization, characterization, and application of bio-inspired Au NPs with an exotic shape (bipyramid, AuBP) and coated with a thin layer of wool-extracted keratin (Ker-AuBPs). The newly developed Ker-AuPBs are characterized in terms of morphological, spectroscopic, and thermo-optical properties. Furthermore, in vitro experiments performed on a human glioblastoma cell line (i.e., U87-MG), using viability assays, confirm the biocompatibility of Ker-AuPBs and localized photo-thermal heating capabilities.

Marine and freshwater diatoms contribute massively to global primary production with significant effects on carbon, oxygen, and silica cycles. Diatoms are enclosed in a micro- and nano- patterned silica shell, the frustule, whose functions comprise mechanical stability, sorting of nutrients from harmful agents, and optimization of light harvesting. In the present work several numerical and experimental techniques including wide-angle beam propagation method, transmission imaging, digital holography, fluorescence imaging, and photoluminescence spectroscopy have been exploited to study the interaction of light with both bare frustules and living cells of the benthic diatom Ctenophora pulchella.

Imidacloprid is the most widely used insecticide in agriculture and its intensive use over the last 30 years has provoked a rising global concern for its potential effects on the ecosystem. In this paper we propose a very efficient, sensitive and specific Localised Surface Plasmon Resonance system for the insecticide detection based on 2D nanostructured metasurfaces with extremely performing plasmonic properties showing a competitive limit of detection lower than 1 ng/ml.

Droplets microfluidics is broadening the range of Lab on a Chip solutions enhancing the portfolio of technologies not only relying on imaging techniques for optical based monitoring. Opto-microfluidics droplets systems have stepped into the niche of microanalytical analysis paving the way for additional solutions.
Progress in combining integrated optics and microfluidics will be presented with special care to those platforms able to detect, label and characterize droplets.
Current applications and future perspectives of opto-microfluidic droplets will be discussed as well as a look behind the scene in creating a functional system.
