DSM VitroStealth® Coating Test Results Indicate Its Potential in the Design of Biosensing Devices

Tue, 10/25/2011 - 10:29am

BERKELEY, Calif.--(BUSINESS WIRE)--DSM, a global leader in biomedical materials, today announced that new test results indicate its VitroStealth® coating can be used in the design of biosensors, such as those for continuous glucose monitoring. VitroStealth® coating is a durable and non-fouling coating designed to prevent unwanted protein absorption and cellular adhesion on synthetic surfaces. Study data indicates that VitroStealth® coating does not inhibit the transport of glucose or oxygen through coated filters. This opens the door to its application in the design of biosensors, where permeability and non-fouling are important requirements.

With these characteristics, VitroStealth® coating is expected to improve the performance of long-term, in-vivo diagnostic devices like biosensors. For example, VitroStealth® coating is designed to prevent protein adhesion, thereby increasing the longevity of biosensors and extending the time of accurate signal transmission. The device can remain in the patient for a longer period of time, which improves cost efficiency. VitroStealth® coatings characteristics also indicate its application in the design of in-vitro diagnostics, such as point-of-care capillaries, blood capillaries and microfluidic devices, and ex-vivo tools, such as blood filters and pre-filled syringes.

"As DSM continues to break new ground in biomedical materials and technology we are excited to expand VitroStealth® coating further in the medical diagnostic arena though collaborative relationships with innovative companies," said John Marugg, Business Manager, Coatings, DSM Biomedical. "The advanced VitroStealth® coating technology has the potential to be used in an expanding array of applications that can ultimately help manage or improve the health of patients."
