A joint research team from Skoltech, HSE, MPGU and MISIS has developed a compact sensor for biochemical analysis, opening up a new frontier in the development of the "lab-on-a-chip." Using bovine serum albumin film as an example, the researchers proved that the chip surface can be adapted for selective analysis of multicomponent solutions. Along with enabling accurate blood tests with only 3 to 5 microliters of blood, the chip will help doctors to detect specific disease markers. The study was published in Analytical Chemistry.
