Abstract
Because of their photo-optical distinctiveness and biocompatibility, gold nanoparticles have proven to be powerful tools in various nanomedical applications. In this article, we discuss the advantage of gold nanoparticles in image diagnostic application of melanoma. It has demonstrated the potential role of gold nanoparticles in the study of tumour tissue architecture and the utility of gold nanoparticles in the hystopathological exam of B16 melanoma with the benefit of fluorescence emission of gold nanoparticles in UV spectrum. The optical properties of colloidal gold nanoparticles allow spectroscopic detection and identification of melanoma cells. The method proposed is easy, inexpensive and reliable for hystopathological analysis of melanoma. The fluorescence images in the cryosections of tissues depicted a strong luminescence property of gold nanoparticles uptaken in melanoma, results that confirm the role of the gold nanoparticles in biological labelling and imaging applications. To emphasize the AuNPs influence over the biological tissues, a study of the chemical bonds configuration was performed using Raman spectrometry.
