Preparation and characterization of poly(ε-caprolactone) nanospheres containing the local anesthetic lidocaine
(Journal of Pharmaceutical Sciences, 2013-01-01) [Artigo]
The objective of this work was to develop a modified release system for the local anesthetic lidocaine (LDC), using poly(ε-caprolactone) (PCL) nanospheres (NSs), to improve the pharmacological properties of the drug when ...
Chitosan/tripolyphosphate nanoparticles loaded with paraquat herbicide: An environmentally safer alternative for weed control
(Journal Of Hazardous Materials, 2014-08-15) [Artigo]
Paraquat is a fast acting nonselective contact herbicide that is extensively used worldwide. However, the aqueous solubility and soil sorption of this compound can cause problems of toxicity in nontarget organisms. This ...
Screening of Formulation Variables for the Preparation of Poly(epsilon-caprolactone) Nanocapsules Containing the Local Anesthetic Benzocaine
(Journal of Nanoscience and Nanotechnology, 2011-03-01) [Artigo]
In this work we describe the screening of four parameters in the preparation, by nanoprecipitation, of poly(epsilon-caprolactone) nanocapsules, used as a drug carrier system for the local anesthetic, benzocaine. A 2(4-1) ...
Evaluation of the effects of polymeric chitosan/tripolyphosphate and solid lipid nanoparticles on germination of Zea mays, Brassica rapa and Pisum sativum
(Ecotoxicology and Environmental Safety, 2017-08-01) [Artigo]
Although the potential toxicity of many metallic and carbon nanoparticles to plants has been reported, few studies have evaluated the phytotoxic effects of polymeric and solid lipid nanoparticles. The present work described ...
Zein nanoparticles and strategies to improve colloidal stability: A mini-review
(Frontiers in Chemistry, 2018-01-01) [Artigo]
Zein, a protein extracted from maize, can be employed to easily produce nanoscale particles suitable for use as carrier systems. This review investigates the main methods for obtaining zein nanoparticles, as well as the ...
