Description
Book SynopsisThe only book to cover adhesion in pharmaceutical, biomedical and dental fields The phenomenon of adhesion is of cardinal importance in the pharmaceutical, biomedical and dental fields. A few eclectic examples will suffice to underscore the importance/relevance of adhesion in these three areas. For example, the adhesion between powdered solids is of crucial importance in tablet manufacture. The interaction between biodevices (e.g., stents, bio-implants) and body environment dictates the performance of such devices, and there is burgeoning research activity in modifying the surfaces of such implements to render them compatible with bodily components. In the field of dentistry, the modern trend is to shift from retaining of restorative materials by mechanical interlocking to adhesive bonding. The book contains 15 chapters written by internationally-renowned subject matter experts and is divided into four parts: Part 1: General Topics; Part 2: Adhesion in Pharmaceutical Field; Part 3:
