Host-guest complexation of a nitroheterocyclic compound with cyclodextrins: a spectrofluorimetric and molecular modeling study
(Journal of Inclusion Phenomena and Macrocyclic Chemistry, 2010-04-01) [Artigo]
Nitroheterocyclic compounds (NC) were candidate drugs proposed for Chagas disease chemotherapy. In this study, we investigated the complexation of hydroxymethylnitrofurazone (NFOH), a potential antichagasic compound, with ...
Desenvolvimento e caracterização de nanocápsulas de poli (L-lactídeo) contendo benzocaína
(Química Nova, 2010-01-01) [Artigo]
In this paper we describe the preparation poly (L-lactide) (PLA) nanocapsules as a drug delivery system for the local anesthetic benzocaine. The characterization and in vitro release properties of the system were investigated. ...

This review article discusses the use of nanotechnology in combination with botanical insecticides in order to develop systems for pest control in agriculture. The main types of botanical insecticides are described, together ...
Polysaccharides as safer release systems for agrochemicals
(Agronomy For Sustainable Development, 2015-01-01) [Resenha]
Agrochemicals are used to improve the production of crops. Conventional formulations of agrochemicals can contaminate the environment, in particular in the case of intensive cropping. Hence, there is a need for controlled-release ...
Neem oil based nanopesticide as an environmentally-friendly formulation for applications in sustainable agriculture: anecotoxicological perspective
(Science of The Total Environment, 2019-04-24) [Artigo]
Sustainable agriculture encourages practices that present low risks to the environment and human health. To this end, zein (corn protein) can be used to develop nanocarrier systems capable of improving the physicochemical ...
Can atrazine loaded nanocapsules reduce the toxic effects of this herbicide on the fish Prochilodus lineatus? A multibiomarker approach
(Science of The Total Environment, 2019-01-29) [Artigo]
Atrazine (ATZ) is a widely used herbicide that has the potential to contaminate the environment and cause deleterious effects on non-target organisms. Release systems for ATZ have been developed to minimize this contamination, ...
