A multifunctional information procurement system was made to create analog reference and acquire information synchronously under various excitation cycles. The as-obtained TP signal was after that proceeded using a common quadrature demodulation/ lock-in analysis to decode amplitude and phase details. Normal TP stage as well as amplitude images of LFA strip were shown in Number 4D at 2 Hz of laser frequency, where the control and also test bands and the surrounding history can be resolved. Because of the different number of GNPs built up in those three areas, the corresponding thermal contrast could be observed in both images. Therefore, the variant of comparison in the examination bands from different strips was used to correlate with the concentration of GNPs as well as analyte. Under the enhanced inflection frequency, the ordinary stabilized stage signal lowers quantitatively as a function of hCG focus. Statistically, 0.2 mIU hCG in LFA could be detected through TPLI strategy, while only 2 mIU hCG was gotten to by aesthetic analysis or optical visitor.
