Evaluation of the Genotoxicity of Chitosan Nanoparticles for Use in Food Packaging Films
(Journal of Food Science, 2010-08-01) [Artigo]
The use of nanoparticles in food packaging has been proposed on the basis that it could improve protection of foods by, for example, reducing permeation of gases, minimizing odor loss, and increasing mechanical strength ...
Nanopartículas de alginato como sistema de liberação para o herbicida clomazone
(Química Nova, 2010-01-01) [Artigo]
In this paper, we describe the preparation of alginate nanoparticles as a delivery system for the herbicide clomazone. Two different methods were investigated and characterized by size distribution, zeta potencial, pH and ...
Characterization of Atrazine-Loaded Biodegradable Poly(Hydroxybutyrate-Co-Hydroxyvalerate) Microspheres
(Journal of Polymers and the Environment, 2010-03-01) [Artigo]
Polyhydroxybutyrate-co-hydroxyvalerate microspheres (PHBV-MS) were prepared as a delivery system for the herbicide atrazine (ATZ). Characterization of the system included investigation of in vitro release properties and ...
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. ...
Polymeric alginate nanoparticles containing the local anesthetic bupivacaine
(Journal of Drug Targeting, 2010-11-01) [Artigo]
Bupivacaine (BVC; S75-R25, NovaBupi<SU (R)</SU) is an amide-type local anesthetic. Sodium alginate is a water-soluble linear polysaccharide. The present study reports the development of alginate/bis(2-ethylhexyl) sulfosuccinate ...
