Strategies for passivating microneedle-based sensors: development, characterization and comparison

Simone Iadanza

Microneedles (MNs) are sharp, pillar-like structures shorter than 1 mm. They can painlessly pierce the stratum corneum (SC), the outermost layer of the skin, and interface with the underlying dermal interstitial fluid, rich in biomarkers. Due to these prop ...

Simulation and Fabrication of Monolithic III-V Photodetectors on Si: The Role of Growth Facets and Localization of Heterojunctions

Kirsten Emilie Moselund, Simone Iadanza

In this work, we provide important parameters to take into account when fabricating in-plane III-V photodetectors (PDs) integrated on silicon (Si) using template-assisted selective epitaxy (TASE). Their performance has previously been demonstrated, and her ...
