Poly(epsilon-caprolactone)nanocapsules as carrier systems for herbicides: Physico-chemical characterization and genotoxicity evaluation
(Journal of Hazardous Materials, 2012-09-15) [Artigo]
The toxicity of herbicides used in agriculture is influenced by their chemical stability, solubility, bioavailability, photodecomposition, and soil sorption. Possible solutions designed to minimize toxicity include the ...
Use of Biopolymeric Membranes for Adsorption of Paraquat Herbicide from Water
(Water, Air, and Soil Pollution, 2012-07-01) [Artigo]
The use of membranes prepared with alginate and chitosan to adsorb paraquat aqueous solution was evaluated as a potential alternative technique for remediation of contaminated water. Production of bilayer membranes was ...
Benzocaine-loaded polymeric nanocapsules: Study of the anesthetic activities
(Journal of Pharmaceutical Sciences, 2012-03-01) [Artigo]
This paper describes a comparison of different polymeric nanocapsules (NCs) prepared with the polymers poly(d,l-lactide-co-glycolide), poly(l-lactide) (PLA), and poly(e-caprolactone) and used as carrier systems for the ...
