Nanoparticles for fingermark detection: an insight into the reaction mechanism.

This publication presents one of the first uses of silicon oxide nanoparticles to detect fingermarks. The study is not confined to showing successful detection of fingermarks, but is focused on understanding the mechanisms involved in the fingermark detection process. To gain such an understanding, various chemical groups are grafted onto the nanoparticle surface, and parameters such as the pH ...

Small interfering RNA delivery by polyethylenimine-functionalised porous silicon nanoparticles.

In this study, thermally hydrocarbonised porous silicon nanoparticles (THCpSiNPs) capped with polyethylenimine (PEI) were fabricated, and their potential for small interfering RNA (siRNA) delivery was investigated in an in vitro glioblastoma model. PEI coating following siRNA loading enhanced the sustained release of siRNA, and suppressed burst release effects. The positively-charged surface im...

Metal-containing nanoparticles and nano-structured particles in fingermark detection.

This article reviews the application of metal-containing nanoparticles and nano-structured particles to fingermark detection. This area of research is attracting significant interest as advances in nanoscience are being incorporated into the field of forensic fingermark detection. Although more research is needed before some of the techniques presented can be implemented in routine casework, na...

Gold Nanoparticles for SERS in Fingermark Identification

This note demonstrates the power of the PerkinElmer RamanStation 400 in combination with a SERS methodology to detect fingermarks on a number of substrates.
