1. Modification of microcapsules for controlled release
Sammanfattning : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER
2. Poly(Lactide-co-Glycolide) in Controlled-Release Pharmaceuticals - Release Mechanisms
Sammanfattning : Controlled-release formulations reduce the frequency of injections and better maintain plasma concentrations within the therapeutic window. Poly(D,L-lactide-co-glycolide) (PLG) is currently the most frequently used biodegradable polymer for this application. LÄS MER
3. Structure control by phase separation and influence on mass transport in films for controlled release
Sammanfattning : Controlled release coatings for oral pharmaceutics are often made of cellulose derivatives. Such coatings can be used to promote a prolonged therapeutic concentration in the blood by a slow drug delivery in the gastrointestinal tract. LÄS MER
4. Controlled Release Gel Formulations for Mucosal Drug Delivery
Sammanfattning : Drug delivery to nasal or ocular mucosa for either local or systemic action faces many obstacles – these routes are protected by effective mechanisms. Gel formulations with suitable rheological and mucoadhesive properties increase the contact time at the site of absorption. LÄS MER
5. Enhanced edible films of mixed biopolymers for controlled release
Sammanfattning : In recent years there has been a growing interest and increased intensity of research in the area of edible films and coatings. Edible films and coatings can improve quality and shelf-life of food products by acting as barriers to e.g. moisture and oxygen, hence preventing dehydration and oxidative reactions. LÄS MER
