Scientists create dual-modality microbeads to improve identification of disease biomarkers
...le. "These nanoparticles enter the pores of the microbeads
so quickly and so completely -- essentially more than 99 percent of the nanoparticles go into the pores of the beads," explained Shuming Nie, the head researcher on the project and the Wallace H. Coulter Distinguished Chair in Biomedical Engineering ...
Growth factor stimulates rapid extension of key motor neurons in brain
...dding it to culture dishes or placing IGF-1-coated microbeads
right next to CSMN cell bodies ?both increased the growth of axons by 15- to 20-fold, reaching the very fast rates previously seen only during initial development. Blocking the interaction between IGF-1 and its receptor reduced axon growth to contro...
Tagging pathogens with synthetic DNA 'barcodes'
...ched many DNA probes to the surface of polystyrene microbeads
5.5 microns (millionths of a meter) in diameter. The results can be read in several ways. One is in a flow cytometer, in which samples move rapidly past a window where a computer reads the color codes of individual beads. Another is by dot blotting, ...
