Light Article

NIST Inventors
Babak Nikoobakht
Methods are disclosed for uniformly charging nanocrystals. Using these methods large area interfaces per nanocrystal can be formed for electrically powering or operating nanocrystals. The formed metal- interfaces, including metal- semiconductor and semiconductor- semiconductor, are structurally

Di-enzymatic Chimeric Endolysin

NIST Inventors
Zvi Kelman
Bacteriophage-derived endolysins have great potential as alternative antimicrobial agents for Gram-positive bacterial infectious diseases, as they are peptidoglycan hydrolases that can destroy susceptible bacteria when applied exogenously. Due to the modular structure of endolysins, engineering
