A recent study published in Nano Letters proposed a novel technique that combines Raman spectroscopy, acoustic bioprinting, and machine learning for rapid bacterial identification. This innovative technique promises improved clinical diagnosis, safer food, faster drug development, and enhanced environmental monitoring.
Many gases are colorless and odorless, which means that leakage can readily go undiscovered. It is essential to utilize detectors that can calculate the concentrations of recognized gaseous species in a target atmosphere in many sectors that handle or manufacture gaseous species. This article discusses the properties and importance of laser-based gas analysis technologies.
