Characterization of pH in normal and dyplastic tissue. pH-dependent fluorescence ratios of Au NC-SNARF at 580 and 640 nm wavelengths (λ 580 nm/λ 640 nm) at various pHs (standard curve) (a) and pHs in normal (applied with mineral oil alone) and oral dysplastic (applied with DMBA in mineral oil) tissues, determined by topically applying Au NC-SNARF using multi-modal delivery methods and comparing resultant fluorescence ratios by confocal microscopy at 580–640 nm wavelengths in the tissues using confocal microscopy (b)
