recommendations! Published in 2019 at "Acta Diabetologica"

DOI: 10.1007/s00592-019-01363-0

Abstract: Aim To identify the potential metabolite markers in diabetic retinopathy (DR) by using gas chromatography coupled with time-of-flight mass spectrometry (GC-TOFMS). Methods GC-TOFMS spectra were acquired from vitreous and aqueous humor (AH) samples of patients… read more here.

DOI: 10.1016/j.microc.2020.105089

Abstract: Abstract Cicada wings exhibit several intriguing properties that arise from a combination of nanopillar structures and chemical constituents, including superhydrophobicity, as well as antimicrobial, antireflective, and self-cleaning functions. While the physical dimensions of the nanofeatures… read more here.

DOI: 10.1021/acs.analchem.2c05243

Abstract: In time-of-flight mass spectrometry (TOFMS), ion detection is often achieved via electron multiplication followed by fast analog-to-digital conversion (ADC). This detection approach is chosen over time-to-digital conversion because it extends the dynamic range of TOFMS… read more here.
