Helisal saliva assay [PDF]

Gut, 1997
Editor, —We read with interest the papers by Reilly et al ( Gut 1997; 40: 454–8) and by Christie et al ( Gut 1996; 39: 27–30) focusing on the Helisal saliva assay (Cortecs Diagnostics, UK) for the diagnosis of Helicobacter pylori infection. These papers reported that this test has a sensitivity of 84–88% and a specificity of 70–71%.

Label‐Free SERS Fingerprinting of Neuroprotein Conformational Dynamics in Human Saliva

Advanced Materials, EarlyView.
Galvanic molecular entrapment (GME) is a label‐free method for detecting and quantifying neuroprotein conformational states. This technique enables direct surface binding and in situ hotspot generation around molecules, effectively overcoming challenges related to target localization and mismatched hotspot geometries.
