Nanoparticles have an enormous potential for the development of applications in biomedicine such as gene or drug delivery. We developed and characterized NH 2 functionalized CdSe/ZnS quantum dot (QD)-doped SiO 2 nanoparticles (NPs) with both imaging and gene carrier capabilities. We show that QD-doped SiO 2 NPs are internalized by primary cortical neural cells without inducing...
Physiological patterns of the extracellular matrix protein, laminin-1, were obtained on glass substrates by physisorption-assisted microcontact printing. Besides the well-retained antigenicity confirmed by indirect immunofluorescence assays, we investigated the supramolecular organization of the proteins by atomic force microscopy. We found the characteristic protein self-assembling in polygonal networks...
