RE: [DIYbio] DIY nanodrop alternative?

My next spec would be a project like that...using a set of standards like the Qubit (0 and 5ug) to calibrate the device and a really good ADC.

You could go the Qubit route and use a blue excitable intercalating dye like Midori Green and a blue LED. The expensive or hard to find part would be the sensor to detect the green within the blue. Filtering the light post excitation would help...something like an orange filter to block out the blue and let the green shine through. The sensor would need to be around the emission spectra which is very tight to the excitation freq, which is why most blue light boxes use an orange filter. The resolution would be low but comparable to older GeneQuant devices.
