SKIN CANCER BIOMARKER DETECTION BY INFRARED SPECTROSCOPY

摘要

The present invention relates to a method for detection in IR (infrared) spectra of human epidermal skin tissue the presence of the multiplet around 1055 cm⁻¹, i.e. the ratio of intensity of the nucleic acids bands, DNA and RNA, indicative for prognosis, diagnosis and prediction of epidermal skin cancers and precancers. Detection of the multiplet together with patterned appearance of DNA/RNA triad peaks at about 1071, 1084/1085 and 1095 cm⁻¹ additionally indicates relation to certain types of tumour and malignancy, also indicating progression of malignancy and progression towards malignancy.
