Summary

The development of super-resolution microscopy has significantly advanced our understanding of cellular biology, overcoming the diffraction limits of traditional light microscopes. This technology enables scientists to visualize details within living cells, such as proteins and DNA structures, down to 100 nanometers or less. Key findings include new cellular structures like the membrane-associated periodic skeleton in neurons and varying surface proteins on lysosomes that suggest additional functions. Research using this microscopy has also enhanced knowledge of gene accessibility in DNA and improved cancer therapy targeting by revealing specific surface receptors on tumor cells. Furthermore, super-resolution techniques are being used to unravel virus infection mechanisms, potentially aiding in antiviral drug development. The advancement of these methods marks a new era in biological discovery, prompting revisions in textbooks and further research into diseases like ALS and cancer.
