文摘

Carboxymethyl cellulose (CMCel) was used as the surface-modifier biomolecule for fluorescent nanocrystal of ZnCdS. ZnCdS/CMCel nanohybrids using a single-step eco-friendly water process were developed. Novel stable colloidal core-shell nanostructures based on ZnCdS/CMCel were produced. CMCel behaved as biological functional macromolecule rendering biocompatible and fluorescent ZnCdS quantum dots. ZnCdS/CMCel core-shell nanostructures demonstrated luminescent activity for cancer cell bioimaging.
