Nanoparticles make insecticides safer

12 Dec 2011

Nanoparticles could be used to deliver insecticides, according to researchers in Australia.

The team loaded mesoporous silica nanoparticles with an insecticide called imidacloprid and used it to clear termites from wood. They found that 80% of the termites were cleared by controlled release from the particles over 48 hours. Current insecticides, such as DDT, bioaccumulate and cause environmental damage – encapsulating insecticides in nanoparticles prevents this.

Decorated graphene for sensors

07 Dec 2011

By RSC Internet Services.

Nanoscale ‘HOT’ Communication

Roya Maboudian and co-workers have developed an easy and versatile way to decorate graphene with metal nanoparticles via electroless deposition.

This method has been used in the fabrication of a gas sensor which, although not optimised, has successfully detected hydrogen sulfide.

The authors believe that their decoration process could be used with existing roll-to-roll fabrication methods for the mass production of sensors.

Graphene–nanoparticle sensors made simple

07 Dec 2011

By Heather Montgomery, Deputy Editor.

HOT Nanoscale Communication

Maboudia and co-workers describe a simple method for decorating graphene with metal nanoparticles. The graphene is grown by a chemical vapour deposition method on a copper substrate, then the copper is used as a reducing agent for the electroless deposition of a noble metal – the authors used gold, platinum, palladium and silver.

The method has the advantages of allowing controlled, reproducible and homogeneous surface coverage.

The authors show that a gas sensor produced using this method is capable of detecting H₂S, and they intend to develop the work to produce electrochemical biosensors.

Biomimetic nanoparticles – the medicine of the future

05 Dec 2011

By Heather Montgomery, Deputy Editor.

Nanoparticles (NPs) show potential as carriers of drugs to specific locations in the body. In order to achieve this without being rejected by the body, they may be “disguised” by coating their surface with a layer which is biocompatible.

Gong and Winnik describe the strategies which have been used to produce these coated NPs and their application, as well as suggesting some future prospects for this exciting research area.
