The term "zwitterionic polymers" refers to polymers that bear a pair of oppositely charged groups in their repeating units. When these oppositely charged groups are equally distributed at the molecular level, the molecules exhibit an overall neutral charge with a strong hydration effect via ionic solvation.

Current Urology Reports, 2003
Biomaterials such as urethral catheters, urethral stents, and ureteral stents are commonly used in patients with urologic disorders. There are currently many different bulk materials and coatings available for the manufacture of urinary tract biomaterials; however, the ideal material has yet to be discovered.

Journal of the American Chemical Society, 2005
We report on the incorporation of microfluidic structure within a high-water-content hydrogel [4% (w/v) calcium alginate]. We used the microfluidic network to control the chemical environment within the hydrogel and demonstrated higher rates of delivery and extraction of solutes than was achievable by diffusion alone.

The situations in which biomaterials are currently used are vastly different to those of just a decade ago. Although implantable medical devices are still immensely important, medical technologies now encompass a range of drug and gene delivery systems, tissue engineering and cell therapies, organ printing and cell patterning, nanotechnology based ...

Chitosan [a (1----4) 2-amino-2-deoxy-beta-D-Glucan] is a unique polysaccharide derived from chitin. Several attempts have been made to use this biopolymer in biomedical field. The use of this material in the development of hemodialysis membranes, artificial skin, drug targetting and other applications are discussed.

One conclusion that might be drawn from a review of the role of biomaterial failure in total hip arthroplasty is that the fracture, wear, and corrosion of materials often serve as the primary causes of failure of hip replacements. It is not yet possible, however, to conclude the prevalence or time course of these failures.

SUMMARY The advent of total hip replacement has presented new problems in the compatibility of biomaterials. For the first time, as many as three different materials are used in juxtaposition. Compatibility signifies that mutual interactions of the body and the implant cause little if any changes in either one.

Convergent advances in the fields of synthetic chemistry, soft matter, molecular self-assembly, and the -omics era point to a new generation of synthetic biomaterials that are indistinguishable in form and function from biological matter. Such living biomaterials comprise a "Holy Grail" of the chemical sciences that will transform both modern medicine ...

This chapter reviews some important properties of collagen-rich tissues. Collagen is a multifunctional family of proteins of unique structural characteristics. The collagen-rich tissues can be thought of as a composite polymeric material in which the highly oriented crystalline collagen fibrils are embedded in the amorphous ground substance of ...
