The development of systems which can release active pharmaceutical ingredients in response to physiological variation has been to the forefront of drug delivery research recently. The development of negative temperature sensitive hydrogels has gained most attention in recent times. This book focuses on the development of novel amphiphilic hydrogels synthesised using photopolymerisation, a fabrication technique commonly used in industrial settings. Hydrogel development especially when pertaining to drug delivery is an area that encapsulates a wide array of scientific backgrounds including polymer chemistry, biomedical engineering and pharmaceutics but to name a few. This work should therefore be ideally suited to professionals in Biomedical and Pharmaceutical fields involved in hydrogel synthesis and characterisation, and would be of particular interest to researchers engaged in ‘smart’ temperature controlled drug delivery applications.
