Portable Neural Network Enabled Biofluid Spectroscopy

There is a wide range of methods for monitoring, diagnosing, and assessing diseases and conditions. One emerging non-invasive approach is biofluid-based analysis. There is a large array of methods that utilize biofluid assessment to diagnose and monitor conditions. Of these methods, few can provide multiplexed and accurate metabolic detection on biofluids, and the approaches capable of this use bulky and expensive technology. These methods are also limited in the data they collect by their inability to be integrated into wearable devices. Existing devices are not able to be used for real-time monitoring.

Researchers at the University of California Davis have developed a new method of biofluid assessment which combines an array of miniaturized spectral detectors that are compatible with machine learning and neural network processing. Although initially used for head and neck cancers, it can be expanded to classify, monitor, and provide diagnostic sensitivity for a broad range of metabolic conditions. This novel approach makes multiplexed metabolic detection possible. It utilizes biofluids that can be collected with non-invasive or minimally invasive methods to accurately and sensitively detect molecular signatures of circulating metabolites excreted in biofluids, enhancing accuracy through multiple biofluids which take advantage of the multi-source neural networks.
