Clarkson Team Designs Liposome-Based Drug Delivery Systems with Built-in Logic

 A model drug delivery system with novel biocatalytic interface has been designed by a team of students headed by Dr. Güray Güven. Recent advances in signal processing with cascades of enzymatic reactions realizing logic gates, such as AND, OR, etc., as well as progress in networking these gates and coupling of the resulting systems to signal-responsive liposomes have opened new controlled drug release opportunities. Liposomes attract considerable attention due to their potential applications in medicine (e.g., nanodelivery systems) and in synthetic chemistry (e.g., nanoreactors). Particularly for drug delivery to specific tissues and organs, a localized, triggerable and controlled compound release by chemical or physical stimuli can be an important attribute for efficient therapies. Chemical and physical stimuli comprise for example redox, pH, temperature, ultrasound, light and acoustic triggered compound release. The present result opens the way to tune the switchable model compound release from pH-sensitive liposomes controlled by biochemical signals logically processed by biomolecular computing systems. The team advised by Dr. Güven continues the work to apply the developed approach for liposome encapsulated systems in enzymatic biofuel cells. The research is being performed under the general supervision of Professor Evgeny Katz as part of a CAMP program at Clarkson University.

CAMP to Sponsor Sixteenth International Symposium on Chemical - Mechanical Planarization  

CAMP will sponsor its Sixteenth International Symposium on Chemical-Mechanical Planarization during the month of August.  The three-day symposium/workshop will be held (August 7-10, 2011) at the Crowne Plaza Resort & Golf Club in Lake Placid, New York.  It will include presentations by industrial and university representatives and a poster session.  The workshop, to be held in a Gordon conference type format, will focus on several fundamental aspects of chemical-mechanical planarization including particle and colloidal aspects, polishing mechanisms, pad/conditioning behavior, flow characterization, Cu/barrier film planarization, defects and post-polish cleaning, low-k films and integration issues, 300 mm wafer issues, MEMS / MOEMS, as well as STI, Nitride/Poly, etc. polishing.  

The co-organizers of this year’s International CMP Conference are S.V. Babu (Distinguished University Professor and CAMP Director, Clarkson University), Manabu Tsujimura ( Director and CTO of Ebara Corporation in Japan), Jin-Goo Park ( Professor, Department of Materials Engineering at Hanyang University), Donald Canaperi (Senior Engineer at  IBM),  Joseph Steigerwald (Intel Fellow; Technology and Manufacturing Group and Director of Chemical Mechanical Polish Technology), Matt Prince (Principal Engineer, Intel), Lee Cook (Technology Fellow, Dow Electronic Materials), and Anurag Jindal (CMP Process Engineer, Micron).
