      The Encyclopedia of Biomedical Polymers & Polymeric Biomaterials presents state-of-the-art research and development on the application of novel polymers in a vital area. This groundbreaking work includes the insight of a large number of contributors from around the world who offer a broad-based perspective on a multitude of : Munmaya Mishra. In this paper, polymer−mesoporous silica nanoparticles have been synthesized by a dual-template technology. Cationic polymer quaternized poly[bis(2-chloroethyl)ether-alt-1,3-bis[3-(dimethylamino)propyl]urea] (PEPU) and anionic surfactant sodium dodecyl sulfate (SDS) were used to form a homogeneous comicelle system to induce mesoporous silica spherical nanoparticles with Cited by:

Introduction Bioadhesion can be de ned as a phenomenon of interfacial molecular attractive forces amongst the surfaces of the biological substrate and the natural or synthetic polymers, which allows the polymer to adhere to the biological surface for an ex-tended period of time [1 4].Cited by:   Polymeric NPs have attracted much attention for their ability to deliver drugs as well as being biodegradable. 7 Among cationic water-soluble polymers available, chitosan is one of the most extensively studied polymers. 1 Recently, further studies have been focused on using nanoparticles in cell culture. 30 Chitosan showed significantly lower Cited by:

    Applications of Polymers in V aginal Drug Delivery Conclusion The vagina is a useful site for the delivery of drugs, but it is still underutilised. Irina Negut, Gabriel Socol, in Nano- and Microscale Drug Delivery Systems, Polymerization. Polymerization methods generally used for the preparation of MPs include bulk, emulsion, suspension, and interfacial polymerization. In the case of the bulk polymerization technique, one or more monomers are heated to induce polymerization in the presence of a catalyst.

This book presents these important facts: a) The mechanism of anionic polymerization, a more than year challenge in polymer chemistry, has now become better understood; b) Precise synthesis of many polymers with novel architectures (triblock, multi-block, graft, exact graft, comb, cyclic, many armed stars with multi-components, dendrimer-like hyper-branched, and their structural mixed (co.

Abstract. Polyanions are polyelectrolytes with negative charges that reside on pendant groups attached to the backbone of the polymer chain. Both natural polyanions such as heparin and heparinoids and synthetic polyanions such as polyacrylic acid and pyran produce a variety of biological activities which have been discussed in detail [1,2].Cited by: Synthesis and Self-Assembly of the pH-Responsive Anionic Copolymers for Enhanced Doxorubicin-Loading Capacity Meijun Yi Key Laboratory of Synthetic and Natural Functional Molecule Chemistry of Ministry of Education, College of Chemistry and Materials Science, Cited by: 3.

Polymeric drug delivery system _____ Some interactions of natural and synthetic anionic polymers with biologically active substances Summary Anionic polymers are nowadays extensively used in.

Anionic surfactants work best to remove dirt, clay, and some oily stains. These surfactants work following ionization. When added to water, the anionic surfactants ionize and have a negative charge.

The negatively charged surfactants bind to positively charged particles like clay. Anionic surfactants are effective in removing particulate soils [11]. Nonionic surfactants are particularly efficient at removing.

Polymer therapeutics is a term used to describe an increasingly important area of biopaharmaceutics in which a linear or branched polymer chain behaves either as the bioactive (a polymeric drug) or, more commonly, as the inert carrier to which a therapeutic is covalently linked, as in the case of polymer-drug conjugates, polymer-protein conjugates, polymeric micelles, and multicomponent by: Anionic addition polymerization is a form of chain-growth polymerization or addition polymerization that involves the polymerization of monomers initiated with anions.

The type of reaction has many manifestations, but traditionally vinyl monomers are used. Often anionic polymerization involves living polymerizations, which allows control of structure and composition. Drug Deliv, ; 23(9): –. Informa UK Limited, trading as Taylor & Francis Group.

As a representative polymeric surfactants, block copolymers consisting of a PEO chain (A) and a polypropylene (PPO) chain (B) have been thoroughly exist various combinations of A and B, typically diblock AB and triblock ABA.

A range of molecular structures can be tuned by the degree of polymerization of A and B. Hydrophilic ABA-type polymer surfactants are used in commercial. In contrast to pharmacologically inert polymers used in most drug delivery applications, polymeric drugs are polymers that exhibit pharmacological activity that can be harnessed for therapeutic benefits.

As the pH value of different microenvironments may vary in living body, pH‐sensitive polymers have been employed as drug delivery systems, aiming at site‐specific drug release. The ionization/deionization of the polymers depends on the pH value of the environment, which leads to the change of polymer : Xintao Shuai, Du Cheng.

1. Introduction. Polymeric carriers have been applied in drug delivery to improve circulation time, alter biodistribution, reduce metabolism, and facilitate cellular internalization of drug cargo [, ].The pharmacokinetics of polymeric carriers and their cargo depend on polymer properties including molecular weight, dispersity, charge, functionalization, and self-assembled size and shapeCited by: 1.Cellulose nanocrystals (CNCs) are one of the most promising natural derived nanomaterials that possess a number of advantages such as nanoscale size, rich of surface functional groups, biodegradability, low cost, and desirable biocompatibility.
