The protein α-synuclein plays an important role in Parkinson’s and other neurodegenerative diseases. Although a considerable amount is known about the structure of the protein within the Parkinson’s-typical amyloid deposits, nothing was known about its original state in the healthy cell up to now. High-resolution nuclear magnetic resonance and electron paramagnetic resonance spectroscopy have helped to visualise the protein in healthy cells.

A chip-based device can generate a laser signal with frequencies spaced in a comb-like fashion. In general, light and water waves alike stretch out and dissipate as they move further and further away from their source. However, there is a type of wave that maintains its shape as it propagates: solitons.

Medical testing has been undergoing a quiet but extensive metamorphosis as labs adopt the versatile technology mass spectrometry, which enables more precise diagnosis. A special issue of Clinical Chemistry, titled “Clinical Mass Spectrometry: Achieving Prominence in Laboratory Medicine”, showcases recent medical advances that this technology has made possible.

In this platform, an aqueous or oil droplet containing gold nanoparticles and captured analytes is allowed to evaporate on a slippery substrate, leading to the formation of a highly compact nanoparticle aggregate for surface enhanced Raman scattering (SERS) detection.
