Accelerated protein retention expansion microscopy using microwave radiation
mycolabadmin
Scientists have developed a faster way to examine brain tissue at extremely small scales using a combination of expansion microscopy and microwave radiation. Instead of waiting days for tissue samples to process, the new method cuts the time down to hours while maintaining the same quality of detailed images. The technique was successfully tested on tadpole and fruit fly brains, showing it could be useful for studying neural structures and potentially applied to studying brain diseases like Alzheimer’s.
