According to the recent reports, scientists have combined the light-based analytical methods with microfluidic sample processing- a Lab-on- a-Chip system- that can clearly identify bacterial strains and their resistance, in less than three hours. Standard diagnosis of the infectious diagnostics requires up to 72 hours as the number of pathogens in patient’s sample are often small to conduct various tests. The analysis is therefore only possible after time-consuming cultivation.
According to the researchers, distinct changes in the Raman spectra can significantly detect whether the strain is resistant or sensible, and the needed concentration of the antibiotic to constrain bacterial growth- which are important diagnostic parameters that influence the success of a treatment.
