Researchers have developed porous silicon nanoparticles (PSiNPs) that can serve as an autonomously functioning delivery platform in biological systems. By synthesizing PSiNPs through silver-assisted electroless chemical etching of silicon nanowires, the team created rod-shaped particles with a cyclodextrin-based nano-valve that opens at acidic pH levels. This innovative design enables the

Microbial communities in different stages of treatment processes in desalination plants were examined by researchers in Irvine, California. They found that bacterial communities in the SWRO membrane biofilm were dominated by filamentous bacteria of the genus Leucothrix mucor, accounting for nearly 30% of the clone library. The rest of the

Researchers from the University of California have been studying the effects of interferon beta (IFN beta) therapy on rheumatoid arthritis (RA). Despite its effectiveness in multiple sclerosis and murine models of arthritis, systematic IFN beta treatment induces only minimal improvement in RA. To understand this paradox, the researchers evaluated the
