Gold-coated glass slides combine an electrically insulating glass substrate with a functional metallic surface, making them highly versatile for laboratory research and sensor development.
Au-coated glass can serve as a base for biosensors, chemical sensors, thin-film sensors, surface functionalization, nanomaterial deposition, electrochemical studies, plasmonics and optical-electrical experiments.
The gold surface also provides an established interface for thiol-based surface functionalization, making gold-coated glass particularly useful for biointerface and surface-chemistry research.
Typical Applications
Biosensors — Functional gold surfaces for biomolecular immobilization and sensor development.
Thin-Film Research — Conductive substrates for polymers, metal oxides, nanoparticles and functional materials.
Surface Functionalization — Gold interfaces for chemical modification and molecular attachment.
Plasmonics — Metallic thin films on optically accessible substrates for optical and plasmonic studies.
Electrochemistry — Conductive Au surfaces for experimental electrode and interface studies.
Sensor Development — Starting surfaces for electrical, electrochemical and hybrid sensing devices.
Choose gold-coated glass when you need a versatile conductive surface with optical access and electrical insulation.

Frequently asked questions
Can the glass or quartz IDE be reused?
Reuse depends on the deposited material and cleaning method. Aggressive chemicals, abrasion and repeated sonication may damage the metal pattern or adhesion layer. A cleaning protocol should be validated on a spare device before routine reuse.
Can I solder wires directly to the gold pads?
Direct soldering may damage a thin-film electrode. Spring contacts, conductive epoxy, anisotropic conductive materials or a compatible connector fixture are generally safer. The selected connection method should be tested for contact resistance and mechanical stability.
Is quartz always better than glass?
No. Quartz provides advantages under specific thermal and optical conditions, but glass is often the more economical and practical choice for routine room-temperature sensing.
Can Schnaiffer change the IDE geometry?
Yes. Custom chip size, finger geometry, active area and contact-pad layout can be reviewed. Custom production depends on fabrication feasibility and order volume.
Request the IDE catalogue, dimensional drawings, price quotation or custom-design review.
