Near-infrared spectroscopy (NIRS) is a noninvasive method used to monitor changes in hemoglobin concentration and oxygen levels in the body. This technique involves passing near-infrared light, ...

Intracutaneously implanted electrochemical microneedles on wearable patches, such as the Libre Style (Abbott) and Dexcom G6/G7 (Dexcom), have advanced glucose measurements in diabetes management ...

Non-invasive blood glucose sensing can be achieved using mid-infrared spectroscopy, although no practical device based on this method has yet been developed. Here, we propose mid-infrared passive ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...

The sample preparation before conducting an infrared spectroscopy (IR) study is as critical as the study itself, and the samples which are difficult to dissolve in any IR-transparent solvent are mixed ...
