Drug release, concept

This book is a companion volume to Pharmaceutical Technology Controlled Drug Release, Volume 1, edited by M.H.Rubinstein and published in 1987. It focused on the different types of polymeric materials used in controlled release. This book extends these concepts to include drug properties, design and optimization, coating, the effect of food and pharmacokinetics. It also reflects the growing interest in biodegradable polymers in oral and topical formulations and the use of sterile implants. 

The results show that this concept is capable of long-term anomalous diffusion [17]. Further optimization may lead to matrix-type release systems capable of even longer and more constant drug release.

The very large absorption cross-sections of Au nanoparticles give rise to photothermal effects, that is, an increase in local temperature upon plasmon resonance excitation. The concept of Au nanoparticles as photothermal transducers has inspired numerous efforts to develop biomedical applications such as localized hyperthermal therapy,63-65 photothermal contrast agents,66 and optothermally controlled drug release,67-69 and also novel platforms for information storage.70... 

Tissue engineering is a recent discipline that is closely related to cell therapy, but combines knowledge of molecular and cell biology with traditional concepts from biomaterials engineering, bioreactors, biomechanics, and controlled drug release, aiming at the development of new tissues.
