Fitting (nanoparticles) to a T: Single‐stranded DNA poly T (blue, see scheme) was found to be a template for the formation of fluorescent copper nanoparticles (CuNPs, red spheres). The size and fluorescence of these CuNPs could be regulated by altering the length of poly T. Other ssDNAs (green) failed to act as a template for CuNPs and were used to create alternating metallized and non‐metallized...
A simple and fast method for separation of cytochrome C (Cyt-C) has been reported based on the electrostatic adsorption between silica coated magnetic nanoparticles (SMNPs) and Cyt-C. When the solution pH is above 6.0, but below the isoelectric point of Cyt-C (pi = 10.6), SMNPs possess zeta potential below -30 mV and can electrically adsorb positively charged Cyt-C to form SMNPs-Cyt-C complex. The...
Here some progresses of core-shell nanoparticles (NPs) for biomedical applications have been reported. A new synthesis mechanism for preparation of core-shell NPs by using water-in-oil (W/O) microemulsion technique has been investigated. And the applications of the core-shell NPs on cell recognition, oligonucleotide detection, single bacterial detection, pH nano-sensor for single cell, DNA recovery...
