UC Davis team (PI, Gang-yu Liu; co-PIs, Donald Land, Atul Parikh, and Yin Yeh) has acquired and installed of a combined confocal optical and atomic force microscope (CCOAFM). The CCOAFM is the first of its kind from Asylum Research and Olympus America, which allows simultaneous acquisition of high-resolution AFM images and multichannel confocal microscopy images.
Using CCOAFM, UCD researchers Liulevych and Liu were able to perform a single cell mechanics measurement. The compression of cell membrane (blue) nuclei (pink) is clearly visible. The Young moduli and bending constants of cell membrane are extracted from this platform.
