What are polymers in drug delivery?
Polymeric drug delivery system has defined as a formulation or a device that enables the introduction of a therapeutic substance into the body. It improves its safety and efficacy by controlling the rate, time, and place of release of drugs in the body.
What is polymeric system?
Polymer systems consisting of chains containing breakable functions along their backbone are generally composed of both linear and cyclic chains in equilibrium in the presence of a catalyst.
What is polymeric carrier?
A wide variety of polymer carriers have been designed for use as drug transporters, and the type of polymer can be of natural or synthetic origin and self-assembled or synthetically crosslinked (for reviews, see Cho et al. From: Bioconjugate Techniques (Third Edition), 2013.
What is polymeric material?
polymer A substance made from long chains of repeating groups of atoms. Manufactured polymers include nylon, polyvinyl chloride (better known as PVC) and many types of plastics. Natural polymers include rubber, silk and cellulose (found in plants and used to make paper, for example).
What are the 2 types of polymer?
There are two types of polymers: synthetic and natural. Synthetic polymers are derived from petroleum oil, and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted.
What is the major advantages of polymer in polymeric nano particles?
Polymeric nanoparticles offer extensive advantages over conventional systems such as they are generally biocompatible, biodegradable, easy to fabricate, non-toxic, non-immunogenic, and site-specific targeting to particular organs or tissues [212].
What are the 3 types of polymers?
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline.
What are polymeric particles?
Abstract. Polymeric nanoparticles (NPs) are particles within the size range from 1 to 1000 nm and can be loaded with active compounds entrapped within or surface-adsorbed onto the polymeric core. The term “nanoparticle” stands for both nanocapsules and nanospheres, which are distinguished by the morphological structure …
What are the properties of polymeric nanoparticles?
Among different delivery systems, polymeric carriers have several properties such as: easy to synthesize, inexpensive, biocompatible, biodegradable, non-immunogenic, non-toxic, and water soluble.
What is a polymeric nanoparticle?
