ABSTRACT

Biomaterial science is an interdisciplinary eld. During its development, various kinds of newly emerging concepts such as self-assembly and nanotechnology have been introduced into this eld. As a result, biomaterial has been redened again and again [1,2]. By taking the advantages of nanotechnology and biodegradable polymers, biodegradable nanocomposites (BNCs) are prepared and applied as biomaterials. Most BNCs are employed as matrices of drug release, scaffolds of tissue repairing, or carriers of imaging agents. In order to make the status, basic concepts, and methods of BNCs easy to understand, a series of questions and answers is presented.
