Recent advancements of EC-QCL based mid-IR transmission spectroscopy of proteins and application to analysis of bovine milk
(IOS Press, 2018-01)
Background:High emission powers of external cavity-quantum cascade laser (EC-QCL) light sources allow to employ significantly larger path lengths for infrared (IR) transmission measurements compared to conventional ...
Two-dimensional correlation spectroscopy: Fundamentals, applications and perspective
(Soc Brasileira QuimicaSao PauloBrasil, 2006)
Study on antibacterial alginate-stabilized copper nanoparticles by ft-ir and 2d-ir correlation spectroscopy

IR Spectroscopy of b4 Fragment Ions of Protonated Pentapeptides in the X–H (X = C, N, O) Region
(American Chemical Society, 2013-02)
The structure of peptide fragments was studied using “action” IR spectroscopy. We report on room temperature IR spectra of b4 fragments of protonated GGGGG, AAAAA, and YGGFL in the X−H (X = C, N, O) stretching region. ...
Characterization of laser-treated Opuntia using FT-IR spectroscopy and thermal analysis
(2013-04-12)
This paper presents the characterization of Opuntia samples whose thorns were removed by laser pulses. The characterization was performed by Fourier transform infrared (FT-IR) spectroscopy and differential scanning calorimetry ...
Synthesis and spectroscopic characterization of a novel coordination polymer of palladium(II) with pyrazole and azido ligands
(2002-12-01)
The one-dimensional coordination polymer of palladium(II) with pyrazolato (Pz -) and azide (N 3 -) as bridging ligands, of formula [Pd 3(μ-N 3)(μ-Pz) 5] n, has been prepared. From IR and Raman studies it was evidenced the ...

Optical diagnosis of actinic cheilitis by infrared spectroscopy
(2016-12-01)
Actinic cheilitis (AC) is considered a potentially malignant disorder of the lip. Biomolecular markers study is important to understand malignant transformation into squamous cell carcinoma. Fourier transform infra red ...
Beyond Fourier Transform Infrared Spectroscopy: External Cavity Quantum Cascade Laser-Based Mid-infrared Transmission Spectroscopy of Proteins in the Amide i and Amide II Region
(American Chemical Society, 2018-06)
In this work, we present a setup for mid-IR measurements of the protein amide I and amide II bands in aqueous solution. Employing a latest generation external cavity-quantum cascade laser (EC-QCL) at room temperature in ...
