Hyphenated TLC as a Tool in the Effect-Directed Discovery of Bioactive Natural Products

open access: yesApplied Sciences, 2020
Complex samples such as botanical extracts contain hundreds of compounds. Since we can only identify compounds that are stable, extractable, separable and detectable from complex botanical extracts, minimal sample treatment and different detection ...

Combination of small molecule microarray and confocal microscopy techniques for live cell staining fluorescent dye discovery [PDF]

open access: yes, 2013
Discovering new fluorochromes is significantly advanced by high-throughput screening (HTS) methods. In the present study a combination of small molecule microarray (SMM) prescreening and confocal laser scanning microscopy (CLSM) was developed in order to

Targeted versus non-targeted HIV testing offered via electronic questionnaire in a Swiss emergency department: A randomized controlled study.

open access: yesPLoS ONE, 2018
BackgroundIn Switzerland, the national HIV testing recommendations propose targeted testing. Although the emergency department (ED) is mentioned specifically as a site where HIV testing should take place, the testing rate in our ED is 1% of patients seen.

Patroon: Open Source Software Platform for Environmental Mass Spectrometry Based Non-target Screening [PDF]

open access: yesJournal of Cheminformatics, 2020
Abstract Mass spectrometry based non-target analysis is increasingly adopted in environmental sciences to screen and identify numerous chemicals simultaneously in highly complex samples. However, current data processing software either lack functionality for environmental sciences, solve only part of the workflow, are not openly available and ...

Exposomic Biomonitoring of Polyphenols by Non-Targeted Analysis and Suspect Screening

open access: yesAnalytical Chemistry, 2023
Polyphenols, prevalent in plants and fungi, are investigated intensively in nutritional and clinical settings because of their beneficial bioactive properties. Due to their complexity, analysis with untargeted approaches is favorable, which typically use high-resolution mass spectrometry (HRMS) rather than low-resolution mass spectrometry (LRMS).
