"Unlike in the areas like wearable devices; there is less awareness about smart materials among biotechnologists. This compact volume is an attempt to break the silos of bioseparation, biocatalysis, drug delivery, theranostics and nanomaterials so that the cross- talk among these disciplines is facilitated. So much chemistry/biochemistry is being done at nanoliter scale that some appreciation of the behaviour of smart polymeric materials by biotechnologists may lead to the cross-fertilization of ideas. Similarly, molecular biologists have much to contribute as exemplified by the chapter on microfluidics. Most extensive work with smart materials in recent years have emerged in the area of design of controlled drug release systems and tissue engineering. This volume provides an overview but with enough information for both- those already into these areas as well as the ones wanting to quickly learn about state of the art"--
