A miniature nerve probe for brain neurotransmitter sampling

Researchers from the University of Twente designed a microneedle with microchannels that can be used to extract small amounts of liquid samples from local areas of the brain The microneedles are about as thick as human hair Based on the invention, neuroscientists were able to monitor dynamic processes faster (in seconds) and more accurately (in microns) The research results were published in the famous scientific journal lab on a chip The brain is a highly complex system, which is studied by many scientists Neuroscientists have been trying to answer the question, "why does one person have a migraine and the other doesn't?" Dr Mathieu odijk, from the BIOS chip lab team, answers, "to answer such questions, it's important to have a detailed study of how the brain works Neurotransmitters, the chemicals that carry information, play a key role in brain work However, most of the existing methods for monitoring neurotransmitters in the brain are not fast enough or can not meet the local accuracy requirements " The tiny water droplets, designed by Dr odijk and his colleagues, are as thick as human hair and contain microchannels that extract tiny liquid samples from parts of the brain The samples are stored in tiny droplets of oil, about 10 pelts (a millionth of a raindrop) It means that information about neurotransmitters is stored in a chemical store, after which it can be processed and extracted The invention enables neuroscientists to monitor dynamic processes in the brain in seconds and achieve micron level accuracy Recommended conference of editor in chief 2019 (the third) microfluidic chip cutting edge seminar http://meeting.bioon.com/2019microfluid? \token = liaodefeng
