AI Article Synopsis
- A novel two-dimensional surface plasmon resonance (SPR) sensor system allows for multi-point sensing, utilizing advanced beam splitting optics to measure nine points simultaneously.
- Calibration for sucrose demonstrated strong linearity between concentrations of 0-10%, with high correlation factors (0.996-0.998) and a low relative standard deviation (0.090-4.0%).
- The system's detection limits ranged from 1.98 × 10(-6) to 3.91 × 10(-5) RIU, showcasing sensitivity comparable to traditional SPR sensors.
Article Abstract
A novel two dimensional surface plasmon resonance (SPR) sensor system with a multi-point sensing region is described. The use of multiplied beam splitting optics, as a core technology, permitted multi-point sensing to be achieved. This system was capable of simultaneously measuring nine sensing points. Calibration curves for sucrose obtained on nine sensing points were linear in the range of 0-10% with a correlation factor of 0.996-0.998 with a relative standard deviation of 0.090-4.0%. The detection limits defined as S/N = 3 were 1.98 × 10(-6) - 3.91 × 10(-5) RIU. This sensitivity is comparable to that of conventional SPR sensors.
