“…SEIRA bands are based on the chemical functional groups of analytes as each function group has its unique absorption band within the active mid-IR range (4600–400 cm −1 ); consequently, the SEIRA spectrum is considered a fingerprint for molecules [ 31 ]. These fingerprints can be used for the identification and differentiation of molecules [ 32 ].…”

Milk is one of the most important multicomponent superfoods owing to its rich macronutrient composition. It requires quality control at all the production stages from the farm to the finished products. A localized surface plasmon resonance optical sensor based on a citrate-capped silver nanoparticle (Cit-AgNP)–coated glass substrate was developed. The fabrication of such sensors involved a single-step synthesis of Cit-AgNPs followed by surface modification of glass slides to be coated with the nanoparticles. The scanning electron microscope micrographs demonstrated that the nanoparticles formed monolayer islands on glass slides. The developed surface-enhanced infrared absorption spectroscopy (SEIRA) sensor was coupled to artificial neural networking (ANN) for the qualitative differentiation between cow, camel, goat, buffalo, and infants’ formula powdered milk types. Moreover, it can be used for the quantitative determination of the main milk components such as fat, casein, urea, and lactose in each milk type. The qualitative results showed that the obtained FTIR spectra of cow and buffalo milk have high similarity, whereas camel milk resembled infant formula powdered milk. The most difference in FTIR characteristics was evidenced in the case of goat milk. The developed sensor adds several advantages over the traditional techniques of milk analysis using MilkoScan™ such as less generated waste, elimination of pre-treatment steps, minimal sample volume, low operation time, and on-site analysis.

“…Furthermore, repeating the sampling process for confirmation purposes is also easier in case of urine [87,88]. The potential application of ATR-FTIR in the detection and quantification of doping agents in urine samples has been investigated [89,90]. Terbutaline and its precursor bambuterol are tow drugs used in asthma treatment in more than 25 countries [91].…”

“…In 2020, Algethami et al explored the potential use of ATR-FTIR in combination with chemometrics in this type of analyses. It has been demonstrated that this technique can detect and quantify these two drugs in volunteers' urine with a high level of accuracy [89]. Moreover, MT-45 is a synthetic opioid that has been developed in the years 1970s by a Japanese pharmaceutical company to be used as an alternative painkiller for morphine.…”

Contemporary criminal investigations are based on the statements made by the victim and the eyewitnesses. They also rely on the physical evidences found in the crime scene. These evidences, and more particularly biological ones, have a great judicial value in the courtroom. They are usually used to revoke the suspect's allegations and confirm or refute the statements made by the victim and the witnesses. Stains of body fluids are biological evidences highly sought by forensic investigators. In many criminal cases, the success of the investigation relies on the correct identification and classification of these stains. Therefore, the adoption of reliable and accurate forensic analytical methods seems to be of vital importance to attain this objective. Attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) is a modern and universal analytical technique capable of fingerprint recognition of the analyte using minimal amount of the test sample. The current systematic review aims to through light on the fundamentals of this technique and to illustrate its wide range of applications in forensic investigations. ATR-FTIR is a nondestructive technique which has demonstrated an exceptional efficiency in detecting, identifying and discriminating between stains of various types of body fluids usually encountered in crime scenes. The ATR-FTIR spectral data generated from bloodstains can be used to deduce a wealth of information related to the donor species, age, gender, and race. These data can also be exploited to discriminate between stains of different types of bloods including menstrual and peripheral bloods. In addition, ATR-FTIR has a great utility in the postmortem investigations. More particularly, in estimating the postmortem interval and diagnosing death caused by extreme weather conditions. It is also useful in diagnosing some ambiguous death causes such as fatal anaphylactic shock and diabetic ketoacidosis.

“…[24] Furthermore, this technique has application, in combination with multivariate modelling techniques, for the detection of banned substances in urine. [25] The Amide II band, due to CÀ N stretching and NH 2 bending, correlates well to albuminuria levels at high concentrations. [26] However, the prediction of proteins from the direct measurement of urine or dried urine is strongly limited by their low concentration and the presence of major interference such as urea and creatinine.…”

ATR‐FTIR Spectroscopy for Early Detection of Diabetic Kidney Disease

Current screening methods for diabetic kidney disease (DKD), characterized by albumin excretion in urine, are expensive or only identify patients in late disease stages. Hence, there is need for a cost-effective, quick, and portable screening tool which identifies patients at DKD onset. Here we report that ultracentrifugation coupled with infrared spectroscopy and machine learning can identify and quantify low level microalbuminuria in urine samples from a cohort of diabetic patients (n = 155) and controls (n = 22). Independent testing of the methods indicated that classification analysis discriminated between normo-and micro/macroalbuminuric samples with sensitivity of > 91 % and specificity of > 99 %. Regression methods quantified albumin concentration in the samples with error values of 17 and 44 mg/L for normo-and microalbuminuric patients. Using only 700 μL of sample, this approach identifies patients at an earlier stage of disease than a urinary dipstick, whilst also yielding results cheaper and faster than the albumin to creatinine ratio.
