Wavelet Transform Makes Water an Outstanding Near-Infrared Spectroscopic Probe

Wavelet transform (WT) has been proven to be a powerful chemometric method for processing analytical data. In this review, works on the application of WT in near-infrared (NIR) spectrum were summarized, emphasizing structural analysis water aqueous systems. The spectral features can obtained from resolution-enhanced NIR with help WT. Taking advantage resolution enhancement and sensitivity spectroscopy water, different structures obtained, which makes potential spectroscopic probe detect information analyte Using variation temperature, interaction solutes, role chemical bio-processes, such as aggregation proteins polymers, was demonstrated. changes temperature found able reflect biomolecules or polymers analyzing
