DESCRIPTION:Prof. Thomas Krauss\, University of York\, York\, United Kingd
 om\nPhotonic Crystals are the culmination of many fascinating developments
  in Physics\, such as Bragg mirrors\, Bloch modes\, and band structures\, 
 and their ability to control the flow of light has given rise to many appl
 ications\, ranging from light emission to optical switching and quantum co
 mmunications. Here\, we discuss the combination of biosensing with imaging
 \, based on localised guided mode resonances\, where each resonance can be
  considered the pixel of an image. This combination adds an exciting new i
 maging modality to the biophotonics toolkit\, which allows us to image bot
 h cells and the biomarkers they secret in real time. Thinking of each reso
 nance as an imaging pixel also provides a very simple readout mechanism\, 
 where we have now demonstrated nanomolar sensitivities with a device that\
 , in principle\, can be made for £10. Furthermore\, we note that silicon 
 photonic biosensors do not tend to exploit silicon’s obvious ability to 
 conduct electricity\, and we demonstrate the first hybrid silicon photonic
  - electrochemical biosensor.
