In that case, the color of the ink and light can be tuned across a fairly wide spectrum, allowing for shape changes with high specificity. (cen.acs.org)
Single - copy genomic sequences were amplified by a factor of more than 10 million with very high specificity, and DNA segments up to 2000 base pairs were readily amplified. (science.sciencemag.org)
Ideally, the drug should have a shape that is perfectly complementary to a disease - causing target, so that it binds it with high specificity. (sciencedaily.com)
