【Abstract】 The use of quantum dots for biological and biomedical applications is one of the fastest moving fields of nanotechnology today.The unique optical properties of these nanometersized senciconductor crystals make them an exciting fluorescent tool for in vivo and in vitro imaging and sensoric applications,in which traditional fluorescent labels based on organic molecules fall short of providing long-term stability and simultaneous detection of multiple sigals.This review aims to highlight the advances in the structure,preparation and surface modification of quantum dots.更多还原
