Detection of Myoglobin with an Open-Cavity-Based Label-Free Photonic Crystal Biosensor

Figure 2

Typical reflectance spectra of a PC-TIR sensor when a 70 ng/mL myoglobin solution flows through the microchannel on the sensor surface. As the binding occurs on the surface, the resonant wavelength of the reflectance dip shifts to the longer wavelength with time. Three representative curves at times 0, 15, and 37 min are shown.
