Apparatus for performing a sensing application
First Claim
1. An apparatus for performing a sensing application, said apparatus comprising:
- a reservoir to contain a solution;
a dispenser to dispense the solution from the reservoir;
a substrate having a plurality of nano-fingers positioned to receive the dispensed solution, wherein the plurality of nano-fingers are flexible, such that the plurality of nano-fingers are configurable with respect to each other;
an illumination source to illuminate the received solution, an analyte introduced around the plurality of nano-fingers, and the plurality of nano-fingers, wherein light is to be emitted from the analyte in response to being illuminated;
a detector to detect the light emitted from the analytea second reservoir to contain a second solution; and
a second dispenser to dispense the second solution from the reservoir onto a second subset of the plurality of nano-fingers that differs from a subset of the plurality of nano-fingers onto which the dispenser is to dispense the solution from the reservoir, wherein the illumination source is to further illuminate the dispensed second solution and wherein the detector is to detect light emitted from an analyte introduced around the second subset of the plurality of nano-fingers.

Abstract
An apparatus for performing a sensing application may a substrate having a plurality of nano-fingers positioned to receive the dispensed solution , first and second reservoirs, first and second dispensers to dispense first and second solutions from the first and second reservoirs onto first and second subsets of the plurality of nano-fingers. The plurality of nano-fingers are flexible, such that the plurality of nano-fingers are configurable with respect to each other. The apparatus may include an illumination source to illuminate the first and second solutions and an analyte introduced around the plurality of nano-fingers, wherein light is to be emitted from the analyte in response to being illuminated. The apparatus may include a detector to detect the light emitted from the analyte.

12. A method for performing a sensing application on an analyte introduced onto a plurality of nano-fingers, said method comprising:
-
dispensing, from a reservoir, a solution onto a first subset of the plurality of nano-fingers, wherein Raman-active material nano-particles are attached to respective tips of the first subset of the plurality of nano-fingers; dispensing, from a second reservoir, a second solution onto a second subset of the plurality of nano-fingers, wherein Raman-active material nano-particles are attached to respective tips of the second subset of the plurality of nano-fingers; applying heat onto the first solution and the second solution to cause the first solution and the second solution to evaporate, wherein evaporation of the first solution and the second solution causes tips of adjacent ones of the plurality of nano-fingers to be drawn toward each other through capillary forces applied on the tips by the solution, and wherein molecules of the analyte are at least one of trapped between and positioned adjacent to the Raman-active material nano-particles attached to the respective tips that have been drawn toward each other; illuminating the Raman-active material nano-particles and the analyte around the first subset of the plurality of nano fingers to cause enhanced Raman scattered light to be emitted from the analyte; and detecting the enhanced Raman scattered light from analyte near the first subset of the plurality of nano fingers; illuminating the Raman-active nano-particles and the analyte around the second subset of the plurality of nano-fingers to cause enhanced Raman scattered light to be emitted from the analyte near the second subset of the plurality of nano-fingers; and detecting the enhanced Raman scattered light emitted from the analyte near the second subset of the plurality of nano-fingers. - View Dependent Claims (13, 14, 15)
