Advanced Science, EarlyView.An edible biohybrid platform triggers nanoplastics (NPs) aging and agglomeration by in situ generating hydroxyl radicals within the intestine. The enlarged NPs are unable to penetrate the intestine and are subsequently excreted. Simultaneously, probiotic biofilms reinforce the intestinal barrier.

Microbiological characterizations by FT-IR spectroscopy
Nature, 1991Infrared signals of microorganisms are highly specific fingerprint-like patterns that can be used for probing the identity of microorganisms. The simplicity and versatility of Fourier-transform infrared spectroscopy (FT-IR) makes it a versatile technique for rapid differentiation, classification, identification and large-scale screening at the ...

Analysis of Gasolines by FT-IR Spectroscopy
Analytical Chemistry, 1996An experimental and computational protocol was established for the simultaneous determination of several key gasoline properties from a single Fourier transform infrared (FT-IR) spectrum. The study has shown that midband FT-IR spectroscopy combined with multivariate calibration analysis is a versatile, efficient, and accurate technique for the ...

Differentiation of Leishmania species by FT-IR spectroscopy
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2015Leishmaniasis is a parasitic infectious disease caused by protozoa that belong to the genus Leishmania. It is transmitted by the bite of an infected female Sand fly. The disease is endemic in 88 countries Desjeux (2001) [1] (16 developed countries and 72 developing countries) on four continents.

FT-IR spectroscopy: a powerful tool in pharmacology
Journal of Pharmaceutical and Biomedical Analysis, 2002In the present work we report a Fourier Transform Infrared (FT-IR) analysis performed on rat encephalon samples in the CH-OH vibrational stretching region (2400-3800) cm(-1), in order to reveal the presence of a very diffuse commercial benzodiazepine: VALIUM.

Surface Analysis with FT-IR Emission Spectroscopy
Applied Spectroscopy, 1992The technique of infrared emission spectroscopy (IRES) is reviewed and further examined in this study as a surface analysis tool. A system has been designed which allows simultaneous kinetic and in situ infrared emission analysis of catalyst surfaces.

Topical Protectant Evaluation by FT-IR Spectroscopy
Applied Spectroscopy, 1989A unique analytical method for evaluating the effectiveness of topical protectants against penetration by chemical agents has been developed with the use of FT-IR and the horizontal attenuated total reflectance (ATR) accessory. A template was designed which allowed a uniform-thickness layer of topical protectant to be applied to the surface of the ATR ...

FT-IR spectroscopy in catalysis
Acta Physica Hungarica, 1987Supported metal catalysts are opaque to infrared rotation generally below 1200 cm−1 thereby preventing all the very important vibrations involving surface-adsorbate or “metal-ligand” motions from being observed by the conventional transmission technique. The possible methods which do not suffer from these limitations are summarized in this paper.

Computers And Computing In FT-IR Spectroscopy
SPIE Proceedings, 1989The state-of-the-art in inexpensive computing for FT-IR spectroscopy is examined. Problems concerning instrument communications, data transportability, networking using personal computers are explored. The use of personal computers in advanced chemometric applications is examined including applications of discriminant analysis for the classification of
