A Better Tool for the Job: Laser-based Technique to Elucidate the Mysteries of Exosomes

Exosomes are small vesicles released by cells, which contain proteins and genetic materials. They are thought to be involved in various life activities, but current techniques to observe them are expensive and time-consuming. In a recent study, a team of undergraduate students from DGIST, Korea, proved the convenience and effectiveness of laser-based technique in identifying exosomes using exosomes from a less studied cancer type, paving the way for future exosome research.
Despite our great progress in understanding various cellular mechanisms over the last decades, many of them remain unclear. Such is the case for exosomes, small vesicles released by cells that contain genetic materials called “RNA” and various proteins. The roles of exosomes are believed to be very varied and important, both for normal bodily functions and also in the spreading of diseases like cancer. However, exosomes are so small that studying them is challenging and calls for costly ....

Capturing the Contours of Live Cells with Novel Nanoimaging Technique Using Graphene


Nature Methods
Scientists graphene coat cells to keep them alive and wet even in vacuum, significantly advancing the field of bioimaging
Researchers from DGIST have now found a way to keep living, wet cells viable in an ultra-high-vacuum environment, using graphene, allowing


accurate high-resolution visualization of the undistorted molecular structure and distribution of lipids in cell membranes. This could enhance our bioimaging abilities considerably, improving our understanding of mechanisms underlying complex diseases such as cancers and Alzheimer’s. 
With every passing day, human technology becomes more refined and we become slightly better equipped to look deeper into biological processes and molecular and cellular structures, thereby gaining greater understanding of mechanisms underlying diseases such as cancer, Alzheimer’s, and others. ....
