SECM imaging of MMD-enhanced latent fingermarks.
Scanning electrochemical microscopy (SECM) has been used to image latent fingermarks enhanced by adsorption of gold nanoparticles onto which silver is chemically deposited, a process known as "multi-metal-deposition" (MMD).
متن کاملAqueous Nile blue: a simple, versatile and safe reagent for the detection of latent fingermarks.
Nile blue A in aqueous solution undergoes spontaneous hydrolysis to the photoluminescent compound Nile red. This reagent provides a simple and safe approach to the detection of latent fingermarks on porous and non-porous surfaces.
متن کاملShielding a room using aluminum foil
A local hospital was interested in shielding some sensitive equipment and contemplated installing a shielded room. The room under consideration was the typical laminated wood core panel with galvanized steel on both surfaces, with a RF shielded door, honeycomb air vent panels and filters for ac power, telephone and any other signals, meeting the shielding effectiveness requirements of MIL-STD-2...
متن کاملOptical properties of drug metabolites in latent fingermarks.
Drug metabolites usually have structures of split-ring resonators (SRRs), which might lead to negative permittivity and permeability in electromagnetic field. As a result, in the UV-vis region, the latent fingermarks images of drug addicts and non drug users are inverse. The optical properties of latent fingermarks are quite different between drug addicts and non-drug users. This is a technic s...
متن کاملOne step to detect the latent fingermarks with gold nanoparticles.
A simple and environment friendly chemical route for detecting latent fingermarks by one-step single-metal nanoparticles deposition method (SND) was achieved successfully on several non-porous items. Gold nanoparticles (AuNPs) synthesized using sodium borohydride as reducing agent in the presence of glucose, were used as working solution for latent fingermarks detection. The SND technique just ...
