Polymers Revolutionize the Medical World
How have polymers been applied in the medical world?

Adriel Martinez

English IV Ms.Spivey 10/13/2013
Polymers have revolutionized our medical world because they have saved and improved the quality of our lives when applied in medical practices. Polymers are macro molecules composed of more minuscule units called monomers. Polymers can be either synthetic or natural, such as cellulose which is a natural polymer found in plants. Research has shown that replacing natural monomers into synthetic polymers creates polymers that are biodegradable in the human body. This process creates biodegradable polymers. Biodegradable polymers, also known as biomaterials, are polymers that can biodegrade within a living organism without causing harmful effects. Biomaterials are largely utilized in medical applications that undergo degradation by the chemical breakdown of the biomaterial with the reaction of dihydrogen monoxide. This process is also known as chemical hydrolysis (Fergade).
The criterion for selecting a polymer for use as a biomaterial is to match the physical and mechanical characteristics with the time it takes the polymer to degrade. In addition, the requirements for selecting a polymer as a biomaterial are that it does not cause a harmful response in the body, it is metabolized correctly so it leaves no remnants behind, it is easily manufactured into a product, and it has a good shelf life (Fergade). A biomaterial is neither a drug nor a food. Biomaterials play a big role in medical devices that are implemented into our everyday world. Examples of these devices are contact lenses, implants, and pacemakers. Biomaterials are used in orthopedic and dental services, as well as in engineering of tissue scaffolds. (Robinson) Biomaterials are required to have three traits: biocompatibility, biodegradability, and bioresorbability. Biocompatibility is the ability of a material to react in a compatible way with the

    Polymers a large molecules made up of a chain of smaller molecules, known as monomers. The monomers that a polymer is made up of decide its structure and therefore it's function. These monomers are linked and coiled in a very specific manor giving the polymer a specific tertiary structure (an extensively coiled and linked polymer chain caused as a result of the formation of more bonds forming). This tertiary structure is crucial to the function of a polymer as it denotes the necessary shape of the complementary molecule. This is easier explained through an example.…

Biological polymers (proteins, polysaccharides, nucleic acids) and lipids are assembled by dehydration synthesis; they are disassembled into their monomers (or into glycerol + fatty acids in the case of lipids) by hydrolysis reactions.…

    Biopol is stable when stored in air and even humid conditions. When the polymer is exposed to microorganisms found in soil, sewage, river bottoms or other similar environments, the decomposition into carbon dioxide and water may occur. Other properties of Biopol include its insolubility in water, good oxygen permeability, ultra violet resistance but poor resistance to acid and bases, solubility in chloroform and other chlorinated hydrocarbons, biocompatibility (hence making it suitable for medical applications), melting point of 175 °C and glass transition temperature of 15°C, sinks in water, and is non-toxic.…

    Polyvinyl Ethanoate Essay

    • 1805 Words
    • 8 Pages

    A polymer is a large molecule comprised of numerous smaller molecules. It is possible for these large molecules to be linear, moderately branched, or highly interconnected. In the latter case the structure progresses into a large three-dimensional complex. The small molecules that serve as the basic building blocks for these large molecules are known as monomers (See Figure 1.1). An example of the relationship between a monomer and polymer is the commercially important material polyvinylchloride, which is comprised of the monomer vinyl chloride. The repeat unit in the monomer generally corresponds to the monomer from which the polymer was made. As with any rule, there are exceptions. For example, polyvinylchloride is formally thought to be made up of vinyl alcohol (CH2CHOH) repeat units; but factually, there is no such monomer as vinyl alcohol. The suitable molecular unit exists in the tautomeric form, ethanal (CH3CHO). In order to make this polymer, it is required that polyvinyl ethanoate is firstly prepared from the monomer vinyl ethanoate, and then to hydrolyze the product to yield the polymeric alcohol.…

    Physical entrapment of bioactive molecules in biomaterials is the most commonly used strategy. To date, different delivery vehicles, including polymeric microparticles, liposomes, hydrogels, foams, and bone cements, have been used for physically entrapping bone growth factors [35]. In the physical entrapment strategy, diffusion and scaffold degradation are the two possible mechanisms for fast release of GFs. Otherwise, the affinity of biomolecules to biomaterials could induce sustained release of bioactive molecules [7]. Dispersion of biomolecules in different biomaterials has also been used for coating the surfaces of implants [35]. For instance, titanium implants have been coated with poly(D,L-lactide), in order to control the release rate of embedded TGF-β1 and IGF-1 [36]. Besides physical entrapment, adsorption and physisorption are the other mechanisms of protein delivery. For instance, the common method for fabricating a BMP delivery vehicle is impregnation of absorbable collagen sponge with BMP solution [37]. Alternatively, the bioactive molecule could be localized in the scaffold using covalent binding. Moreover, a delivery system that is regulated by an internal stimulus can be designed to control the release rate of biomolecules. Commonly, an appropriate delivery system in tissue engineering applications should…

    This material property is called osteoconductivity. Osteoconductivity is also increased by the structure of the material, as open pores can provide a three dimensional structure for the bone to regrow as the scaffold dissolves. The advantage of bioresorbable osteoconductive bioceramics is that once the patient is healthy there is no need for removal surgery. However their poor mechanical properties preclude them from being used in load bearing applications. The two most critical material properties for orthopedic grafts are osteoconductivity and osteoinductivity, which describe the material’s ability to further promote cell differentiation, proliferation, and formation of bone structures.7 Two things determine osteoconductivity, both the morphology of the material, in particular porosity, as well as its chemical and bioactive properties. Osteoinductivity is provided by locally delivered growth factors and…
