Nucleic Acid Amplification on Paper Substrates

Rapid visual detection of Mycobacterium tuberculosis DNA using gold nanoparticles

“…Hence, these features make colorimetric assays highly feasible compared to traditional detection methods. 5 Nanoparticles used in many of the colorimetric assays are formulated using a noble metal. Due to the quantum and surface boundary effects of these particles, they exhibit different material properties compared to bulk noble metals.…”
