Abstract Photonic crystal surfaces represent a class of resonant optical structures that are capable of supporting high intensity electromagnetic standing waves with near-field and far-field properties that can be exploited for high sensitivity detection of biomolecules and cells. While modulation of the resonant wavelength of a photonic crystal by the dielectric permittivity of adsorbed biomaterials enables label-free detection, the resonance can also be tuned to coincide with the excitation wavelength of common fluorescent tags - including organic molecules and semiconductor quantum dots. Photonic crystals are also capable of efficiently channeling fluorescent emission into a preferred direction for enhanced extraction efficiency. Photonic crystals can be designed to support multiple resonant modes that can perform label free detection, enhanced fluorescence excitation, and enhanced fluorescence extraction simultaneously on the same device. Because photonic crystal surfaces may be inexpensively produced over large surface areas by nanoreplica molding processes, they can be incorporated into disposable labware for applications such as pharmaceutical high throughput screening. In this talk, the optical properties of surface photonic crystals will be reviewed and several applications will be described, including results from screening a 200,000-member chemical compound library for inhibitors of protein-DNA interactions, gene expression microarrays, and high sensitivity of protein biomarkers.

Molecular Imprinting Technique

A “smart” molecular imprinted photonic crystal (MIPC) sensor has been developed based on the combination of photonic crystal (PC) and molecular imprinting technique (MIT). It can give rise to readable optical signals and color changes upon sensing benzocaine with detection limit of 16.5 μg/ml. In fish sample detection, the developed MIPC sensor shows satisfied result accuracy with HPLC. With the advantage of satisfactory specificity, rapid responsiveness and excellent recoverability, this MIPC material shows great potential towards on-site screening and visual detection of trace benzocaine in real sample.
