I am trying to find information on a indicator that detects DNA without using spectrophotometer or any devices. It should work just like a pH indicator where a color change can be seen with our naked eyes. Is there such technology available? I was once told to look for molecular/DNA indicator through the net, but nothing was available. Please help me out on this >.<, Thanks
I am not sure to understand what you want. Just a colored reaction in presence of DNA in solution to quickly have an idea of the concentration, or just presence/absence (that would be problematic, since in most environment you will find mold an bacteria).
I guess you will need to detail more your needs if you ever hope to get a good answer
