EtBr and UV have been used in laboratories for techniques such as agarose gel electrophoresis

However, it has been shown that EtBr is toxic and  potential mutagen

Also, UV can damage DNA sample and UV radiation is harmful

NaBI is optimized for excitation of alternative reagent to EtBr with 470 nm Blue LED replacing UV light

Its compact size helps make better use of a space in the laboratory

Also, the program has been designed considerably simple for ease of use
