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 ...
متن کاملAIE luminogen-functionalised mesoporous nanomaterials for efficient detection of volatile gases.
Mesoporous silica nanoparticles functionalised with aggregation-induced emission (AIE) luminogen via a carbon-nitrogen double bond are fabricated into films by a dip-coating method. The as-made films can serve as efficient fluorescent sensors for the naked-eye detection of volatile acid gases by colour and emission changes, as well as for the detection of 2,4-dinitrotoluene vapours by fluoresce...
متن کاملSurface functionalisation of diatoms with dopamine modified iron-oxide nanoparticles: toward magnetically guided drug microcarriers with biologically derived morphologies.
Diatom silica microcapsules prepared by purification of diatomaceous earth (DE) were functionalised by dopamine modified iron-oxide nanoparticles, in order to introduce diatoms with magnetic properties. The application of magnetised diatoms as magnetically guided drug delivery microcarriers has been demonstrated.
متن کاملAerosol assisted chemical vapour deposition of gas sensitive SnO2 and Au-functionalised SnO2 nanorods via a non-catalysed vapour solid (VS) mechanism
Tin oxide nanorods (NRs) are vapour synthesised at relatively lower temperatures than previously reported and without the need for substrate pre-treatment, via a vapour-solid mechanism enabled using an aerosol-assisted chemical vapour deposition method. Results demonstrate that the growth of SnO2 NRs is promoted by a compression of the nucleation rate parallel to the substrate and a decrease of...
متن کاملMetal-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...
