The photonic force microscope (PhFM) is better suited than the atomic force microscope (AFM) to the observation of soft tissues, in particular biological cells. But his resolution was still insufficient. Researchers from the Institute of Electronics and Systems and the Center for Structural Biochemistry obtained high resolution images, thanks to a nanofabrication process of the PhFM tips. The results are published in the journal Nano Letters.
