diffusion for oral extened release by using micelle-forming properties and counter –charge polymer. -how it works: - a highly water soluble drug was added to a gel forming polymer matrix but with a counter polymer which slows down drug diffusion out of the matrix Advantage – for water soluble drugs‚ sustained release‚ simple to make Disadvantage – not for all water soluble drugs‚ make sure that counter-charge polymer does not bind with too high affinity to the drug‚ and does not interact with the drug

Fantastic Plastic an Optimistic Prospect Introduction A. Background of the study A plastic is a type of synthetic or man-made polymer; similar in many ways to natural resins found in trees and other plants. Webster’s Dictionary defines polymers as: any of various complex organic compounds produced by polymerization‚ capable of being molded‚ extruded‚ cast into various shapes and films‚ or drawn into filaments and then used as textile fibers. Plastics are durable that is why most of

development and applications of new organic/inorganic hybrid materials. Polymer-inorganic nanocomposite present an interesting approach to improve the separation properties of polymer material because they possess properties of both organic and inorganic such as good permeability‚ selectivity‚ mechanical strength‚ and thermal and chemical stability. Composite material derived by combining the sol–gel approach and organic polymers synthesis of hybrid material were the focus area of review It has

Sean Byrne Teacher Biology Honors 13 August 2014 Unit 1 Chapter 3 1) a. Monomers are small‚ simple molecules that when put together create carbon compounds‚ and polymers are molecules that consist of repeated units. b. Functional groups are made of clusters of atoms‚ while macromolecules are large polymers. c. A monosaccharide is a simple sugar‚ but a disaccharide is known as a double sugar‚ or two monosaccharaides. d. Long chains of amino acids are called polypeptides‚ and proteins are composed
