Abstract This study demonstrates a biosensing platform facilitated by localized surface plasmonic resonance (LSPR) on silicon (Si) nanopillar metasurface mediated the presence of cephalexin (Cef) antibiotics in solution. The is designed to exhibit narrow quadrupolar Mie resonances that when coupled with bovine serum albumin‐coated (BSA‐coated) gold nanospheres (BSANS) will produce an appreciable redshift at peak wavelength, occurring only target antibiotic. To optimize performance Si...
Beginning from the end of 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic swept all over world and is still afflicting whole global population. Given that vaccine-manufacturing ability limited virus can evolve quickly, vaccination alone may not be able to pandemic, thus developing fast accurate diagnoses effective therapeutics will always unmet needs. Phage display peptide library has been used in screening antigen-specific peptides for invention novel mimic...
A fast, easy-to-implement, highly sensitive, and point-of-care (POC) detection system for frog virus 3 (FV3) is proposed.
