Poly Hema, also known as poly(2-hydroxyethyl methacrylate), is a biocompatible polymer that is widely used in various biomedical applications. It is a hydrophilic polymer composed of repeating units of 2-hydroxyethyl methacrylate, resulting in a three-dimensional network structure.
Poly Hema is highly biocompatible, meaning it is well-tolerated by living tissues and does not elicit significant immune responses or toxic effects. This property makes it an ideal material for a variety of applications in medicine and biology.
One of the major applications of Poly Hema is in the field of contact lenses. It is used as a base material for soft contact lenses due to its ability to absorb and retain water, making the lenses more comfortable and suitable for extended wear. The hydrophilic nature of Poly Hema also allows for the transport of oxygen to the cornea, thereby preventing hypoxia and maintaining ocular health.
Additionally, Poly Hema is used in the development of biomedical coatings, drug delivery systems, tissue engineering scaffolds, and biosensors. Its biocompatibility, along with its ability to easily form hydrogels, makes it an attractive choice for these applications. The hydrogel nature of Poly Hema also enables it to mimic the natural soft tissue environment, facilitating cell adhesion, proliferation, and differentiation.
In summary, Poly Hema is a biocompatible polymer with a range of applications in the biomedical field. Its hydrophilic nature, along with its ability to absorb and retain water, makes it suitable for contact lenses and other biocompatible materials. Its use in various biomedical applications is based on its biocompatibility and ability to form hydrogels, allowing for enhanced functionality and cellular interactions.
