| Abstract: | Electrospun porous films doped with the green-synthesized CdS e quantum dots were synthesized.Glycerol was chosen to prepare the quantum dots( QDs),with the highest quantum yield of 78.28%.Polycaprolactone( PCL) was electrospun with CdS e QDs to avoid the QDs' toxicity and improve the QDs' cytocompatibility.The electrospun QDs-doped films preserve the original QDs' fluorescence.Pores can be detected from the SEM of the films,predicting the possibility of loading drugs in the cancer therapy.The cell proliferation assay shows excellent cytocompatibility of the eletrospun CdS e-QDs-doped films.The present eletrospun CdS eQDs-doped porous films are cytocompatibale,highly-fluorescent and potential to load drugs in cancer therapy. |
