Paper Title:
Aged Fingermarks Detection with CdS/PAMAM Nanocomposites
  Abstract

CdS(Cadmium sulfide)/PAMAM(polyamidoamine) Nanocomposites were in-situ prepared taking PAMAM dendrimers as stabilization in water. The prepared solution containing photoluminescent semiconductor CdS QDs(Quantum dots) was utilized for detection of aged fingermarks on adhesive tape strips. The fingermarks were aged for 1 d, 7 d and 30 d in nature light respectively. The results show that the latent aged fingermarks treated with CdS/PAMAM nanocomposites emit yellow luminescence under ultraviolet excitation of 365 nm in the dark. Aged fingermarks were detected successfully with better resolving rate comparing with existing nano-scale commercial TiO2 powder suspension.
