Renishaw Raman Microscope 1000 (with 632.8 nm light) was employed to characterize Raman spectra of BP material. The thickness of BP nanosheets and BP deposited overlay were measured by AFM (Veeco Instruments Inc., di Dimension 3100). The surface coverage of BP-fiber was measured by SEM (Hitachi, S-520).
For optical interrogation system, broadband light source (BBS: Agilent HP83437A, Agilent Technologies Inc.) was used along with an optical spectrum analyzer (OSA, Agilent HP86142A, Agilent Technologies Inc.). The OSA was connected to a computer and the optical spectra were recorded by a customized program. Data analysis was performed using the customized program which automatically defined resonance wavelength using the centroid calculation method.
All biochemical procedures were performed in a fume cupboard. To minimize the cross-sensitivities of temperature and bend, all experiments were conducted at a controlled room temperature of 22.0 ± 0.1 °C unless specified otherwise, and the fiber device was placed straightly in a custom-made microchannel container and all the chemicals and solvents were added and withdrawn by careful pipetting.
