A recent review article explores how machine learning (ML)-assisted Raman spectral classification is being used in applications such as biomedicine and material analysis.

In this tutorial, we break down these vibrational spectroscopy advancements and what we can expect in the months and years ahead.

The final FDA guidance on Computer Software Assurance (CSA) was released in September 2025. This was followed by an update in Feb 2026 incorporating Quality Management System (QMS) based on ISO 13485:2016. Many proponents particularly outside of the medical device ecosystem have said that CSA will replace Computerised System Validation (CSV). But will it? Really?
