Infrared (IR) spectroscopy is a broadly applicable, composition sensitive analytical
technique. By leveraging the high spatial resolution of atomic force microscopy (AFM), the …

This article focuses on the atomic force microscopy-infrared (AFM-IR) technique and its
recent technological developments. Based on the detection of the photothermal sample …

The advent of nanotechnology, and the need to understand the chemical composition at the
nanoscale, has stimulated the convergence of IR and Raman spectroscopy with scanning …

Viruses are infections species that infect a large spectrum of living systems. Although
displaying a wide variety of shapes and sizes, they are all composed of nucleic acid …

In a cultural heritage context, fatty acids are usually found as breakdown products of lipid-
containing organic remains in archaeological findings, binders in aged oil paintings, and …

Up to 70% of the oil paintings conserved in collections present metal soaps, which result
from the chemical reaction between metal ions present in the painted layers and free fatty …

Optical photothermal infrared (O-PTIR) is a recently developed molecular spectroscopy
technique that allows to noninvasively obtain chemical information on organic and inorganic …

Formation and aggregation of metal carboxylates (metal soaps) can degrade the
appearance and integrity of oil paints, challenging efforts to conserve painted works of art …

Thermal properties of materials are often determined by measuring thermalization
processes; however, such measurements at the nanoscale are challenging because they …

A molecular-level understanding of the structure of the polymeric network formed upon the
curing of air-drying artists' oil paints still represents a challenge. In this study we used a set …
