摘要: We report an in situ method for temperature measurement microfluidic systems using Brownian diffussion of nanoparticles. This is superior its reproducibility and reduced systematic errors as measuring diffusivity does not rely on fluorescence intensity or lifetime fluorophores. Threedimensional mapping was achieved a simple videomicroscopy setup combination with software analysis that enables selective tracking In addition, we successfully demonstrated the capability this noninvasive tool biological samples.
