This Defense Intelligence Agency reference document, dated 31 March 2010 (DIA-08-1003-020), was one of a series of advanced technology reports produced in FY 2009 under the Advanced Aerospace Weapon System Applications (AAWSA) program. It surveys biosensors and BioMEMS, covering brain-implanted neuroelectrodes, drug-delivery pumps, implantable glucose sensors, brain-machine interfaces, retinal prostheses, microfluidic lab chips, NASA cell culture systems, and microcantilever sensors. It concludes that the field is expanding rapidly toward nanomechanical systems.
UNCLASSIFIED/ ,sr&R: &FFliIAk Wi&i Qllb¥ red fluorescent protein (RFP) in E. Coli bacterial cells genetically engineered by ASU microbiologist Dr. Valerie Stout. These bacteria glow when the rec-A gene is active, indicating a certain type of stress or damage to the bacteria due to the space environment. Figure 33. NASA Space Application of Microfluidic Cell Culture System Made by Micromachining (Towe - ASU research) Microcantilever MEMs Sensors The microcantilever is one of the simplest MEMS based biosensor devices, with wide applications in detection of very small amounts of specific chemicals through a process known as affinity sensing. This can detect gas composition, antigens in the air, toxic gases and particulates. The use of microcantilevers as transducers for chemical and biochemical sensing has only become widespread in the last few years, mainly due to their use in the development of microsensor arrays. The idea is quite simple: the surface of the cantilever, a thin rectangular beam clamped at one end, is chemically modified to react with specific compounds. The mass deposition that follows the chemical reaction causes a stress, and this leads to a detectable bending of the cantilever as illustrated in Figure 34. 36 UNCLASSIFIED/ /Pett err1e1111t ~:!I! 9HLY
