Multifunctional Edged-Satellite AuAg Nanoparticles-Based Integration Platform for Screening, Validation, and Elimination of Vibrio Bacteria. [PDF]

Adv Sci (Weinh)
A simple method is developed to synthesize multifunctional nanoparticles (NPs), AuAgNPs with edged satellites (ES‐AuAgNPs). These NPs demonstrate peroxidase‐like (POD‐like) activity, SERS ability, and antibacterial properties. Utilizing these multifunctional capabilities, a portable, syringe‐sized biosensor is created that integrates screening ...

Solar VUV telescope for nanosatellites

Technical Physics, 2022
Within the Universat program, a set of solar vacuum ultraviolet (VUV) telescopes has been developed for deployment on 6U nanosatellites. Telescopes are designed to get images of the solar corona. The spectral ranges of observations is considered, the characteristics of the nanosatellite from the point of view of the observations feasibility are ...
