Bacticount is an application developed with the aim of being a highly sensitive, high-speed, and inexpensive virus detection tool, and detects viruses by combining the "LAMP method", a technology that replicates DNA in large quantities like PCR, with a smartphone camera. possible. The research team has named the virus detection method using Bacticount 'smaRT-LAMP'.

The specific procedure for virus detection by smaRT-LAMP is as follows. First, prepare the equipment necessary for DNA amplification by the LAMP method, such as a hot plate and heat block, and install a smartphone with Bacticount installed on it.

Then, the sample is processed in the same way as the normal LAMP method. At this time, in virus detection using the general LAMP method, virus DNA and fluorescent protein are simultaneously amplified and the presence or absence of the virus is determined by measuring the fluorescence intensity. is measured with a smartphone camera. For this reason, it is possible to determine the presence or absence of viruses without preparing an expensive fluorescence measurement device.

According to the research team, smaRT-LAMP can detect and distinguish between the new coronavirus and influenza virus. In addition, one PCR test costs $ 100 to $ 150 (about 11,500 yen to 17,300 yen), whereas smaRT-LAMP is said to be executable for less than $ 7 (about 800 yen) once. Michael Mahan, a member of the research team, said, ``Testing is essential for pandemic countermeasures because new strains of new coronaviruses have emerged worldwide. Almost half of the world's population has a smartphone. "Today, smaRT-LAMP has the potential to provide fair and equitable access to precision diagnostics."

Bacticount is only compatible with Android at the time of article creation, and can be downloaded from the link below.
