Vibrational spectra of the amide I′ mode of the fully deuterated NMA-d7 show gradual increase of peak frequencies and line broadening as the size of RMs decreases. Analyses of the spectral features reveal the presence of three states of NMA-d7 that correspond to NMA located in the core of...

The OPTIR (~500 nm spot) has a signal-to-noise ratio of around 4000:1 (RMS, considering amide band intensity as the peak and baseline noise at the amide I location measured on a CaF2blank) with ~20 sec accumulations. Microplastics ...

The iC IR software has been developed for time-resolved reaction analysis and integrates a peak picking algorithm with functional group intelligence to considerably decrease the analysis time. Users can integrate their chemistry knowledge with an automated data analysis workflow to guarantee accurate collec...
We have found that the turbidity of PNIPAAM aqueous solution changed gradually with the increase of temperature but increased deeply after 33°C, which may be related to LCST, and the onset of turbidity was not so sharp. Moreover, a clear endothermic peak at 34.5°C was obviously observed ...
The determination of protein-to-lipid ratio by infrared spectroscopy was first proposed by Navarro et al. [30]. Since proteins and lipids show distinctive absorption bands, the FTIR spectrum can be used to estimate the protein-to-lipid ratio by dividing the relative intensity of amide I protein...
deuterium (Figures 4c, 4d). The C-D vibrational peak showed up at around 2100 cm-1— no intrinsic spectral peaks reside in this region. MIP imaging at the C-H and C-D wave numbers revealed the intrinsic and externally treated contents, respectively, at new insights of metabolism in live...
