Thermal and morphological characterization of highly porous nanocomposites for possible application in potassium controlled release
(2018-03-01)
The use of fertilizer and water availability are essential factors limiting the agricultural production. The controlled release technology is very promising because it allows the maintenance of fertilizer concentrations ...
Synthesis and characterization of cellulose acetate from cellophane industry residues. Application as acetaminophen controlled-release membranes
(2021-01-01)
Cellophane film production generates cellulosic residues from scraps, edges, and low-quality films. In this work, cellophane was used as a raw material to produce cellulose acetate (CA). CA was produced through the homogeneous ...
Nanocellulose/palygorskite biocomposite membranes for controlled release of metronidazole
(2021-10-01)
The incorporation of drugs in nanocomposites can be considered a potential strategy for controlled drug release. In this study, a nanocomposite based on bacterial cellulose and the palygorskite clay (BC/PLG) was produced ...
Novel technologies for the encapsulation of bioactive food compounds
(Elsevier Ltd, 2016-02)
Recent advances in nanoscience and nanotechnologies offer a revolutionary approach to the development of novel and healthier foods. Nano-technological and micro-technological carriers based on biomolecules may be tailored ...
Preparation and characterization of poly(ε-caprolactone) nanospheres containing the local anesthetic lidocaine
(2013-01-01)
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 ...
Evaluation of retrograded starch as excipient for controlled release matrix tablets
(2017-08-01)
High amylose starch (HAS) was retrograded by two different methods. The physicochemical properties of the retrograded materials were evaluated and structural changes were highlighted. Micromeritics properties were demonstrated ...
Experimental problems in the application of UV/visible based methods as the quantification tool for the entrapped/released insulin from PLGA carriers
(John Wiley & Sons Ltd, 2009-12)
Background: Controlled release of medicaments from biodegradable polymers remains the most convenient way for their sustained release. Although a number of articles have been published, experimental work involving the ...
Fabrication and characterization of a novel herbicide delivery system with magnetic collectability and Its phytotoxic effect on photosystem II of aquatic macrophyte
(American Chemical Society (ACS), 2020-09-11)
The use of nano- and microparticles as a release system for agrochemicals has been increasing in agricultural sector. However, the production of eco-friendly and smart carriers that can be easily handled in the environment ...
Insights into the impact of cross-linking processes on physicochemical characteristics and mucoadhesive potential of gellan gum/retrograded starch microparticles as a platform for colonic drug release
(2020-02-01)
Polymer microparticles have been regarded a promising system for drug delivery. In this paper, ionic cross-linking (IC) and dual cross-linking (DC) (ionic/covalent) processes were addressed for the design of innovative ...
