We report the synthesis of highly luminescent, water soluble quantum clusters (QCs) of gold, which are stabilized by an iron binding transferrin family protein, lactoferrin (Lf). The synthesized AuQC@Lf clusters were characterized using UV-Visible spectroscopy, X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), photoluminescence (PL), matrix assisted laser desorptio...
BACKGROUND Sentinel lymph node (SLN) biopsy is a routine surgical staging procedure in clinically lymph node-negative breast cancer. Fourier transform infrared (FTIR) spectroscopy, a technique based on the biochemical composition of the tissue, has previously been found to be capable of differentiating between normal and malignant tissue. The aim of the present study was to explore the intraope...
Introduction The absorption of near infrared light by materials provides information about the chemistry and structure of those materials by probing their molecular vibrations. The infrared spectra of biological macromolecules have distinct absorbances that allow Fourier Transform InfraRed (FTIR) spectroscopy to monitor macromolecular changes. FTIR can be carried out in aqueous solution, organi...
Coiled coils of different order were investigated using infrared (IR) spectroscopy. Recently, we demonstrated that dimeric coiled coils display unique vibrational spectra with at least three separable bands instead of only one band of a classical alpha-helix in the amide I region. This was attributed to a distortion of the helical structure by the supercoil bending, giving rise to bands that ar...
