Abstract
Methods and systems for combined SPP and Raman scattering-based bio-detection are provided. Embodiments include a bio-detection system having a microfluidics chip, a Surface Plasmon Polariton (SPP)-based system component, and a Raman scattering-based system component. The SPP-based and the Raman scattering-based system components can be used simultaneously or individually separately to detect biological and/or chemical analytes. The bio-detection system further includes an aerosol collector chip. Embodiments of the present invention can be used aboard means of propagation of biological and/or chemical analytes, including, for example, commercial aircrafts. Embodiments of the present invention can be used to enable an aircraft warning system.

26. A method for bio-detection, comprising:
-
directing light at a microfluidics chip; detecting refractive index changes within said microfluidics chip, wherein said refractive index changes result when bio-receptor molecules within said microfluidics chip bind with analytes; and detecting Raman scattered photons that result from changes in vibrational, rotational, or electronic energy of said bio-receptor molecules when said bio-receptor molecules bind with said analytes. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)
