The 5th Workshop on Recent Issues in Bioanalysis (WRIB) was organized by the Calibration and Validation Group as a 2-day full immersion workshop for pharmaceutical companies, CROs and regulatory agencies to discuss, review, share perspectives, provide potential solutions and agree upon a consistent approach to recent issues in the bioanalysis of both small and large molecules. High quality, better compliance to regulations and scientific excellence are the foundation of this workshop. As in the previous editions of this significant event, recommendations were made and a consensus was reached among panelists and attendees, including industry leaders and regulatory experts representing the global bioanalytical community, on many 'hot' topics in bioanalysis. This 2011 White Paper is based on the conclusions from this workshop, and aims to provide a practical reference guide on those topics.

This study introduces an advanced bioanalytical platform that combines digital microfluidics (DMF) with Raman spectroscopy, effectively addressing common issues in bioanalysis such as sample contamination, excessive consumption of samples and reagents, and manual handling. Our innovative system is engineered to handle diverse sample types and enables both sample preparation and in-situ analysis on a single device, utilizing less than 5 μL of samples and reagents. It incorporates a Translucent Raman Enhancement Stack (TRES) sensor, which boosts the detection signal, and includes droplet-driving functionality for automated processing of complex samples in a compact setting.

Hydrogen peroxide (HO) is suspected to promote cancer. Higher concentrations of HO have always harmed mammalian cells, other living things, as well as the environment. As well, elevated concentrations of HO might cause major health problems such as cancer, cardiovascular disease, asthma, Alzheimer's disease, etc.

Quantitative analysis of peptides in biological fluids offers a high diagnostic and prognostic tool to reflect the pathophysiological condition of the patient. Recently, methods based on liquid chromatography coupled with mass spectrometry (LC-MS) for the quantitative determination of intact peptides have been replacing traditionally used ligand-binding assays, which suffer from cross-reactivity issues. The use of "top-down" analysis of peptides is rapidly increasing since it does not undergo incomplete or non-reproducible digestion like "bottom-up" approaches.
