Abstract
So as to develop an effective tool for tumor imaging, we have embedded quantum dots (QD) in hydrogel nanoparticles. Their uptake in cancer cells has been studied in vitro and in a mice tumor model. Compared with QD alone, the QDs embedded in nanoparticles showed higher uptake in the tumor tissue. This novel conjugate can serve as a good imaging tool and also has the potential to serve as a carrier for drugs.
