Abstract: A method is for detecting a biomarker within a sample of blood. The method may include processing the sample of blood with a microfluidic blood plasma separator and a plasmonic array biosensor, and flowing the sample of blood over a sensing surface of the plasmonic array biosensor. The sensing surface of the plasmonic array biosensor may have an ssDNA aptamer against the biomarker. The method may further include binding the biomarker in the sample of blood to the ssDNA aptamer of the plasmonic array biosensor, and detecting the biomarker in the sample of blood based upon LSPR altering a reflected optical signal from the plasmonic array biosensor.

Abstract: A method for molecular chirality detection is described. The method includes providing a substrate defining an array of hole-disks, each hole-disk coupled with an asymmetric optical cavity. Each asymmetric optical cavity having a back reflector separating a plasmonic pattern by an appropriate selection of thickness. The substrate is illuminated to simultaneously excite two degenerate localized surface plasmon modes producing a strong chiral near-field. The method may also include generating a characterization of chiral molecules on the substrate based on the strong chiral near-field. Substrates and detectors for molecular chirality detection are also described.

Abstract: An electronic device is for identifying the plastic composition of an unknown plastic object. The electronic device may include a spectrometer configured to receive the unknown plastic object and generate a MIR reflectance spectra characteristic of the unknown plastic object, a memory configured to store a multi-spectral fingerprint library for plastic types, and a processor coupled to the spectrometer and the memory. The processor is configured to analyze in real-time the MIR reflectance spectra characteristic of the unknown plastic object, and identify the plastic composition based upon at least comparing the MIR reflectance spectra characteristic of the unknown plastic object to the multi-spectral fingerprint library. The processor may be configured to expand the fingerprint library upon initial baseline characterization.
