Database of FTIR spectra peak assignment for major chemical functional groups

Functional groups on materials and cell surface play important roles in mediating a variety of interactions between different materials as well as between cells and materials. Thus, characterization of type and relative abundance of different chemical functional groups on material and cell surface play important roles in helping us formulate hypothesis governing material-cell interactions, as well as understanding fundamental biomaterial-cell interactions. To this end, Fourier transform infrared (FTIR) spectroscopy is the workhorse instrumented method for characterizing material and cell surface for presence of a broad range of chemical functional groups and their relative abundance. This works reports a small collated database of the wavenumber specific to each type of functional group, which would help facilitate interpretation of FTIR spectrum, as well as semi-quantitative analysis of relative abundance of chemical functional groups.
