The news reporters obtained a quote from the research, "Development of latent fingermarks with the synthesized CdTe/MSA QDs was faster and the ridge details were clearer compared with CdTe/TGA QDs. In addition, latent fingermarks developed with CdTe/MSA QDs showed less background and better contrast than that of gentian violet or rhodamine 6G. Latent fingermarks could be well developed on black tape, scotch tape, tinfoil, aluminum alloy, stainless steel as well as on the adhesive side of yellow tape, even when the latter were aged up to seven days."
According to the news reporters, the research concluded: "As immersion time greatly reduced to 10 s by using CdTe/MSA QDs, a preliminary result of latent fingermark development by spraying was presented also."
