Abstract:
Methods and systems for nanopillar sensors are described. Nanopillars can be defined on a substrate, and metal deposited on the nanopillars. A thermal treatment can reflow the metal on the nanopillars forming metallic bulbs on the top end of the nanopillars. These structures can have enhanced optical detection when functionalized with biological agents, or can detect gases, particles and liquids through interaction with the metal layer on the nanopillars.
Abstract:
The basic structure and functionality of a probe as disclosed herein allows for flexibly incorporating into the probe, various sensing elements for various sensing applications. Two example applications among these various sensing applications include bio-sensing and chemical-sensing applications. For bio-sensing applications the probe, which is fabricated upon a silicon substrate, includes a bio-sensing element such as a nano-pillar transistor, and for chemical-sensing applications the probe includes a sensing element that has a functionalized contact area whereby the sensing element generates a voltage when exposed to one or more chemicals of interest.

Abstract:
A field effect nano-pillar transistor has a pillar shaped gate element incorporating a biomimitec portion that provides various advantages over prior art devices. The small size of the nano-pillar transistor allows for advantageous insertion into cellular membranes, and the biomimitec character of the gate element operates as an advantageous interface for sensing small amplitude voltages such as transmembrane cell potentials. The nano-pillar transistor can be used in various embodiments to stimulate cells, to measure cell response, or to perform a combination of both actions.
Abstract:
Novel methods to fabricate biological sensors and electronics are disclosed. A silicon-on-insulator wafer can be employed by etching a pattern of holes in the silicon layer, then a pattern of cavities in the insulating layer, and then sealing the top of the cavities. Further, n or p doped regions and metallic regions can be defined in the processed wafer, thereby enabling integration of biological sensing and electronic capabilities in the same wafer.
