Analysis of insulin amyloid fibrils by Raman spectroscopy.

The formation of amyloid fibrils from insulin is investigated using drop-coating-deposition-Raman (DCDR) difference spectroscopy and atomic force microscopy (AFM). Fibrils formed using various co-solvents and heating cycles are found to induce the appearance of Raman difference peaks in the amide I (approximately 1675 cm(-1)), amide III (approximately 1220… CONTINUE READING
