本文介绍了一种在分子生物学领域中利用光热效应检测纳米颗粒的明显放大图像的方法，并利用单元件干涉仪对单个生物分子进行检测。纳米颗粒可以通过将光能转换为热能的光热效应来检测。光热效应使得放大纳米颗粒的图像成为可能。它的图像可以使用单元件干涉仪进行鲁棒检测，并基于傅里叶变换方法进行相位分析进行实时检测。利用傅里叶变换方法，获得了光热效应引起的干涉条纹相位变化，从而实现了视频速率下碳微粒位置的检测。
This article describes a method to detect an apparently magnified image of nanoparticles by the photothermal effect and using a single element interferometer for single biomolecule detection in the field of molecular biology. Nanoparticles can be detected by the photothermal effect which is converting light energy to thermal energy. The photothermal effect makes it possible to magnify an image of nanoparticles. Its image can be detected using a single element interferometer for robust detection and performing phase analysis based on the Fourier transform method for real-time detection. This article reports that the phase of interference fringe changed by the photothermal effect was obtained using the Fourier transform method to detect positions of carbon microparticles in video rate.
