Prof. YongKeun Park’s group has developed a novel microscopy technique for the label-free imaging of biological specimens. Based on Kramers-Kronig relations, this new method produces quantitative phase images of biological specimens with an optical microscope simply by controlling the incident angle of illumination....read more
Prof. YongKeun Park’s group has developed a novel method for non-interferometric holographic imaging. The method, based on Kramers-Kronig relations, provides holographic images of biological specimens using an optical microscope simply by controlling the illumination beam....read more
Alterations in morphological, biochemical, and mechanical properties of individual diabetic red blood cells were quantitatively and non-invasively studied employing a 3-D quantitative phase imaging technique. No significant alterations were observed in the morphological and biochemical parameters of diabetic red blood cells compared to the healthy ones. However, membrane fluctuations of the diabetic red blood cells were significantly diminished and exhibited negative correlation with HbA1c levels, implying a deteriorated deformability of diabetic RBCs....read more
