How have polymers been applied in the medical world?

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.…

    Materials in the modern day world assist us with comfortable everyday living. Most people don’t recognise the fact that science is behind all of our modern day advances. Molecular properties and structures form the basis of the functioning of our appliances, materials and environment. The way that these moles are charged, their polarity, state, bonding and forces individualise the material to make them unique in their formation and function. Polymers are chains of monomers (atom or a small molecule that has the potential of chemically binding to other monomers of the same species) which link in various fashions (e.g. cross-link, linear linking) to form materials that are used constantly to help humanity’s comfort and existence thrive. An important innovation of chemical advances is a material known as Hydrogels.…

    The production of Polyhydroxybutyrate is well known in the medical field as it is mainly used for surgical pins and internal suture due to its biocompatibility. It has a high melting point with about 175C, which makes the material compatible as containers with high temperature usage. These properties of being biodegradable meaning its products decompose naturally without surgery needed to remove, and biocompatible meaning the body does not react to this polymer or reject it as a foreign object, are important properties in which often uses no fossil fuel based alternative.…

    6. What’s the biological relevance of dehydration and hydrolysis reactions ― that is of being able to assemble polymers from monomers and to disassemble polymers into monomers? 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.…

    The Polymer Envoys program would be very good for me because it will help me further my education by conducting research and this could help me when I go for nursing school. It can also teach me how to become better at research and help me grow better at my studies of science and learn how to use it. I think this program will teach me how science operates. I really enjoy science and writing research papers. This program can help me in the field I want to further in life and it will become very useful in life. This program seems to be very interesting and helpful to children my age.…

    Biopol is a biopolymer that is an environmentally friendly biodegradable plastic made from renewable resources (made naturally in plants from starch and glucose). Biopol is the brand name for a group of biopolymers often called PHAs or PHBs. The continual use of petroleum to make polymers for plastic will eventually run out and hence Biopol was introduced as a polymer replacement for petroleum. It is made from an organic substance known as Alcaligenes eutrophus which is a microorganism.…

    Polymethylmethacrylate, or PMMA for short, is a polymer consisting of the monomer methyl methacrylate that has been around since the 1930s1. PMMA is a polymer that has a high impact strength, is scratch and shatter resistant, and is relatively lightweight1. Because PMMA can also be formed into a transparent thermoplastic and has a glass transitions temperature of 130oC, this polymer served as a glass substitute in its early uses1. Other beneficial characteristics of Polymethylmethacrylate include its high thermal stability, its resistance to light, and its resistance to acidic and basic degradation1. Because of these beneficial physical and chemical properties, PMMA has a wide range of applications in optics, nanotechnology, industry, and medicine1.…
