Hydrogel Science and Technology for Drug Delivery, Medical Devices and Consumer Products
ID: 726401
New York, USA
Expert’s [particular] expertise comes from background in materials science and extensive experience in all major sterilization processes. He therefore knows the changes in properties of a device, including package, due to sterilization and shelf life. A good example of this is Expert’s extensive experience in developing hydrogels from formulation to process and product. As use of hydrogel in a sterile product, it must overcome the issues of being a growth medium by choice of using antimicrobials. As hydrogels have high water content, the choice of the package is crucial. The interaction the sterilization process has upon the hydrogel has to be considered and operating conditions have to be established. The sterilization dose may not be high enough to achieve the required SAL but if too high may over cure or degrade the product. Another product area where he has made significant contributions is dialyzers. These devices are made of many different polymeric materials, therefore choosing effective materials including the membrane, that will be functional and not be damaged by sterilization is crucial.
