Researchers from Duke University have developed a novel method, surface-initiated enzymatic polymerization (SIEP), for detecting DNA hybridization on a chip. This approach utilizes terminal deoxynucleotidyl transferase (TdT) to incorporate multiple fluorophores into a single-stranded DNA (ssDNA) chain, enabling efficient detection of DNA hybridization. The researchers demonstrated the sensitivity of this

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

Researchers from Duke University have designed and fabricated fiber-optic nanoprobes for optical detection in single living cells. The nanoprobes' sensitivity depends on the extremely small excitation volume, which is determined by the aperture sizes and penetration depths. The researchers achieved nanoaperture diameters of approximately 50 nm using a 25

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 in Blacksburg, Virginia, have successfully synthesized polymer-magnetite nanoparticle complexes that respond to both magnetic fields and temperature. These novel complexes were created using alkyl halide-functional bis(diethylphosphonate) esters as initiators for polymerizing N-isopropylacrylamide via controlled atom transfer radical polymerization. The phosphonate esters were removed after polymerization, resulting in poly(
