Macromolecules are so huge that these are made up of more t or more atoms. Macromolecules are also termed as polymers. They are formed by the polymerisation of molecules such as carbon, hydrogen and oxygen. The monomer units of macromolecules are polar in nature, with their heads and tails with different physical and chemical properties.

Among the wide verity of scaffolding materials, natural or synthetic biopolymers are the most commonly biomaterials mainly due to their unique physicochemical and biological features. In this context, naturally occurring biological macromolecules are particular of interest owing to their low immunogenicity, Cited by: Chitosan is an amino polysaccharide found in nature, which is biodegradable, nontoxic and biocompatible.

It has versatile features and can be used in a variety of applications including films, packaging, and also in medical surgery. Recently a possibility to diversify chitosan properties has emerged by combining it with synthetic materials to produce novel natural-synthetic hybrid Cited by: Since the s when Hermann Staudinger pioneered theories on “macromolecules,” covering both natural and synthetic polymers, this concept captured the imagination of chemists to design a.

This book is a comprehensive study of the subject of ionic interactions in macromolecules. The first parts of the book review and analyze the conventional.

Bacteria that cause bacterial infections and disease are called pathogenic bacteria. They cause diseases and infections when they get into the body and begin to reproduce and crowd out healthy bacteria or to grow into tissues that are normally sterile.

To cure infectious diseases, researchers discovered antibacterial agents, which are considered to be the most promising Cited by: 1.

A macromolecule is a very large molecule, such as protein, commonly composed of the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more.

Chemists can create macromolecules in labs. Most of the synthetic, or made in labs, macromolecules are polymers, which are large molecule built ups from smaller building block molecules, called monomers. On the other hand, living organisms build polymers and others complex macromolecules through natural process.

Synthetic and semi-synthetic polymers Biodegradable synthetic polymers are man-made materials that have found many applications in the biomedical field because of their tailorable properties. They are particularly suitable for tissue engineering applications, because 3D structures of various shapes and sizes can be fabricated from synthetic.Rubber Nanocomposites: Preparation, Properties and Applications focuses on the preparation, characterization and properties of natural and synthetic rubber nanocomposites.

The book carefully debates the preparation of unmodified and modified nanofillers, various manufacturing techniques of rubber nanocomposites, structure, morphology and properties of nanocomposites.Ampholytic polymer: Polyelectrolyte composed of macromolecules containing both cationic and anionic groups, or corresponding ionizable group.

Note: An ampholytic polymer in which ionic groups of opposite sign are incorporated into the same pendant groups is called, depending on the structure of the pendant groups, a zwitterionic polymer, polymeric inner salt, or polybetaine.
