LAMP-AuNP followed by UV-vis spectrophotometry of the corresponding specificity (A) and sensitivity (B) assays in Fig 1B and 1D, respectively. The x-axis represents wavelength (nm). A shift of peak to a higher wavelength was observed for the no-template and negative test results. AuNP, gold nanoparticle probe; HPV, human papillomavirus; LAMP, loop-mediated isothermal amplification.
