These studies suggested that Al nanoslit-based biosensors are more sensitive and suitable than the gold sensor for sensing a large mass analyte, such as cells. Design of the plasmonic biosensor chips for cell sensing The CPALNS4c chip was designed to be used for cell sensing in a microfluidic system. A continuous-flow media supply system was connected to the CPALNS4c chip through the polymethylmethacrylate (PMMA) adaptors (Fig.?2c), thereby enabling long-term observation periods. As shown in Fig.?2f, the GOALNS25c chip was designed to have an open-well format. The well-to-well distance is usually 9?mm, which is compatible with that of 96-well microplates. Additionally, the cover lid was designed to prevent reagent cross-contamination between wells. Thus, the chip may be used with automated liquid handling systems for screening of drugs that modulate cell adhesion.

Optical properties of the nanoslit-based plasmonic biosensors Transmission spectra of the CPALNS4c chip (Fig.?3a,c) and the GOALNS25c chip (Fig.?3d,e) were measured using our CAAS. In the water-filled chamber, the intensity spectrum of the CPALNS4c chip showed a Fano resonance peak and dip at 615?nm and 645?nm, respectively (Fig.?3a,b). When the chambers were filled with air, we observed a peak at 468?nm (Fig.?3b), which is close to the expected wavelength of 470 nm24. For the GOALNS25c chip, specific and obvious dips were observed in the intensity spectrum and transmission spectrum when the chip was in contact with water. Although the transmission spectra represent the feature of the resonance of nanoslit sensors, we used the intensity spectra to analyze the kinetics of cell adhesion. The use of intensity spectra for the analysis simplified the process and the spectral difference could be observed while the artifact from the light source was subtracted. The Fano resonance spectrum of the Al nanoslit-based biosensor is Cysteamine HCl usually comprised of the 3-mode coupling resonance of Cavity resonance, Woods anomaly and SPR24. In the previous study, Fano resonances could be easily modulated in CPALNS sensors by changing the ridge height of nanoslits and the deposited metal film thickness. Depending on the ridge height and the metal thickness, the transmission spectrum could range from a Woods anomaly-dominant resonance (peak) to an asymmetric Fano profile (peak and dip) or an SPR-dominant resonance (dip). Moreover, the differential wavelength shifts of the localized-SPR peak and dip are determined by the period of the nanoslit sensor24. In this study, the transmission spectrum indicates that this Fano resonance of the CPALNS biosensor is an asymmetric Fano profile (peak at 610?nm, dip at 644?nm) (Fig.?3b), while the GOALNS biosensor shows an SPR-dominant (dip at 638?nm) resonance (Fig.?3e).
