Optical and structural properties of cadmium sulphide quantum dots based thin ﬁlms as potential sensing material for dengue virus E-protein

In this work, cadmium sulfide quantum dots composited with polyamidoamine dendrimer (CdSQDs-PAMAM) thin film had been successfully developed for use in the detection of dengue virus (DENV) E-proteins. Studies involving XRD, EDX, UV–Vis-NIR, and AFM analyses proved the presence of CdSQDs and PAMAM na...
