Abstract:
A photonic band-gap nanosensor based on porous silica is proposed in the study. The photonic band-gap silica nanosensor is easy to fabricate and simple to use. Its optical characteristics can be easily modulated by electrochemical etching and its large internal surface area can be easily modified by different types of biomolecules. The photonic band-gap silica nanosensor can be fabricated on silicon substrates for the detection in bio-microsystems or transferred to conventional glass slides for naked-eye measurement using inverted microscopes. The photonic band-gap silica nanosensor can provide inexpensive, label-free, real time, simple to use and high-throughput assays for biomolecular reactions. The advantages of low cost, high sensitivity and versatile use in the photonic band-gap silica nanosensor make it surpass SPR and porous silicon interferometry biosensors
