Abstract
A label-free multiplexed sensing platform is based on light interaction with aperiodic photonic structures with an advantage of a broadband operation. Multiple-scattering-induced 'fingerprinting' colorimetric signatures can be used as a transduction mechanism. Aperiodic sensing platforms can operate in the infrared to provide an overlap with spectral fingerprints of biological molecules. Miniaturized optical biosensors may be based on engineered colorimetric scattering signatures (structural color), sharp spectral features, non-uniform angular distributions of scattered light, and broadband manipulation of the local density of states in nano-textured scattering surfaces with deterministic aperiodic order. The biosensors can be fabricated in semiconductor, metal, low- and high-index dielectric platforms using standard nanofabrication techniques such as electron-beam lithography, ion-beam milling, etc, and can be replicated over large areas by standard nano-imprint lithography.
