Exploration of utility of combined optical photothermal infrared and Raman imaging for investigating the chemical composition of microcalcifications in breast cancer
We aim to develop a protocol for efficiently analysing breast microcalcifications and their microenvironment in detail by combining O-PTIR and Raman spectroscopy at the same time, the same location and the same high resolution (0.5 μm).

Electrostatic assemblies of molecularly imprinted polymers on the surface of electrospun nanofiber membranes for the point-of-care detection of thiodiglycol, a sulfur mustard poisoning metabolic marker
In this study, a new method for the point-of-care testing of thiodiglycol (TDG) using molecularly imprinted polymer (MIP)-coated electrospun nanofiber membranes is reported.
