Every published revision of every detection approach on this website. Current revisions are linked from the main tab navigation; archived revisions keep stable URLs.
🟢 Currently recommended
| Revision | Approach | One-sentence description | Status | Pages |
|---|---|---|---|---|
| v2 · 2026-08 | 1 · Glutamate Oxidase | Direct enzyme biosensor on bare, electrochemically activated screen-printed carbon; glutamine → H₂O₂ is detected amperometrically at +0.6 V vs Ag/AgCl, with no nanomaterial amplification layer. | Recommended | |
| 2026-08 | 2 · Ammonium ISE | Differential ammonium ion-selective electrode biosensor using dual NH₄⁺-ISEs against a K⁺ reference; glutamine → NH₄⁺ via immobilised Pseudomonas sp. glutaminase. | Recommended |

| v1 · 2026-08 | 1 · Glutamate Oxidase | MWCNT/CuO/chitosan multilayer on screen-printed carbon for H₂O₂ signal amplification; superseded after CuO and MWCNT edge-plane sites were found to catalyse direct amino-acid oxidation independent of the enzymes. | Archived |
Versioning convention
- Each revision is a complete, independent set of protocol pages.
- The current recommended revision lives at the bare filename (for example,
materials.html). - Archived revisions are immutable copies at
-YYYY-MM-suffixed filenames (for example,materials-2026-08.html). The suffix is the snapshot month. - Every protocol page carries a footer stamp
Revision: YYYY-MM · <architecture short-name>so users always know which version they're reading. - Archived pages display a banner at the top of the body that points at the current recommended revision.
Adding a new revision
To publish a new revision, snapshot the current *.html pages to *-YYYY-MM.html, update the LIVE files for the new design, and add a row to the table above. The convention does not require any tool changes.
