摘要:
MEMS devices fabricated using inexpensive substrate materials such as paper or fabric, are provided. Using paper as a substrate, low cost, simple to prepare, lightweight, disposable piezoresistive sensors, including accelerometers are prepared. Signal-processing circuitry can also be patterned on the substrate material.The sensors can be utilized as two-dimensional sensors, or the paper substrate material can be folded to arrange the sensors in a three dimensional conformation. For example, three sensors can be patterned on a paper substrate and folded into a cube such that the three sensors are orthogonally positioned on the faces of a cube, permitting simultaneous measurement of accelerations along three orthogonal directions (x-y-z). These paper-based sensors can be mass produced by incorporating highly developed technologies for automatic paper cutting, folding, and screen-printing.Also provided are methods of modifying paper for use as a substrate material in MEMS devices.

A simple interfacial nano-biosensing strategy for high-sensitivity detection of low-solubility compounds like 17β-estradiol is disclosed. Apparatuses, methods and compositions for detection incorporate a combination of droplet microfluidics with aptamer-functionalized GO nanosensors.
摘要:
Certain embodiments are directed to a point-of-care (POC) microfluidic biochip for rapid, highly sensitive and specific pertussis diagnosis. The POC biochip can be used in various venues such as physician's office, schools, hospitals, and low-resource settings so that rapid prevention and treatment of pertussis can be achieved. The POC biochip based pertussis diagnosis is low-cost and does not rely on any specialized instrument, but offers comparable sensitivity to real-time PCR.
