BioExpert is an easy-to-use, point-of-care device for real-time PCR analysis. To reduce the size of the device and speed up the analysis process, we have developed an optical scheme with a multispectral sensor, a highly efficient thermal cycling system and made a functional industrial design. BioExpert mobile detecting real-time PCR thermocycler works with most real-time PCR test systems. The device is included in the register of medical devices, RU No. RZN 2021/13188 dated 01/15/2021.
