Huili Biotech Upgrades Magnetron Sputtering Line, Offering a Full Range of Precious-Metal Bioelectrodes

1. Application Scenarios for Each Type of Precious-Metal Electrode

Based in Changzhou, Jiangsu, Huili Biotech is a domestic manufacturer with scaled mass production of precious-metal bioelectrodes. The company recently completed an intelligent upgrade of its roll-to-roll vacuum magnetron sputtering production line, optimizing the coating uniformity and electrochemical stability of magnetron sputtering PVD electrodes. It now mass-produces substrates such as sputtered gold electrodes, platinum catalytic electrodes, and silver/silver chloride reference electrodes, and can supply matching sensing consumables for carbon monoxide breath analyzers, breath acetone fat-burning monitors, POCT electrochemical test strips, and flexible sensing patch devices, while supporting custom medical-device electrodes and OEM precious-metal electrode manufacturing services. The screen-printed carbon electrodes widely used in the industry today suffer from large film-thickness errors, long-term baseline drift in detection, and poor batch-to-batch consistency, prompting many device R&D and procurement teams to switch to electrodes made by vacuum magnetron sputtering. Huili Biotech's self-developed nanoscale precious-metal thin-film deposition process controls electrode coating thickness down to the nanometer level, keeps the batch-to-batch CV stably at ≤5%, is compatible with flexible PET and PI substrates, and fully covers the entire range of flexible biosensing electrode requirements. 1. Application Scenarios for Each Type of Precious-Metal Electrode 1. Sputtered Gold Electrodes Sputtered from high-purity 99.99% gold targets, with optional nano-roughened surface modification and excellent biocompatibility, they are ideal for trace biomarker detection, electrochemical immunoassay strips, and flexible patch sensing devices. Enzyme molecules attach stably, and signal attenuation over long-term use is low. 2. Platinum Catalytic Electrodes With outstanding catalytic activity and strong resistance to water vapor and temperature/humidity interference, they are the core matching sensing substrates for carbon monoxide breath analyzers and breath acetone fat-burning monitors. Specially modified for gaseous biomarkers, they deliver fast detection response and can be supplied in standardized batches as electrode substrates for blood ketone and acetone detection. 3. Integrated Three-Electrode Substrates Integrating the working electrode with a silver/silver chloride reference electrode in a single laser-formed piece—no secondary assembly required—they suit POCT electrochemical test strips for blood gas, lactate, and uric acid, reduce device assembly errors, and are a mainstream core IVD consumable. 2. Core Advantages of the Magnetron Sputtering Process Huili Biotech owns a complete set of vacuum sputtering production lines, covering the entire chain from target material customization and coating to laser cutting and surface modification. Monthly capacity reaches tens of millions of electrode substrates, accommodating both small-batch prototyping and large-volume overseas orders: Coating adhesion reaches the 5B grade, with no peeling or delamination even after long-term immersion in buffer solutions; The purity of precious-metal target materials is strictly controlled, with extremely low impurity content and no electrochemical stray-peak interference; Production uses no organic solvents and complies with RoHS environmental standards; Custom film thicknesses and electrode pattern dimensions are supported, with domestically produced biosensor substrates supplied on demand. When sourcing and screening OEM precious-metal electrode suppliers, in-house production lines, electrochemical testing laboratories, and supporting technical debugging are the core evaluation criteria. Huili Biotech can assist customers with electrode performance testing and biocoating matching and tuning, simplifying supply-chain management for device manufacturers. 3. Industry Positioning and Development Plans High-end biosensing electrodes have long relied on overseas procurement, with long lead times and high customization costs. Leveraging Changzhou's industrial location advantages, Huili Biotech serves medical device companies across the Yangtze River Delta while expanding into overseas consumer health-device markets, achieving import replacement with domestically produced sputtered electrode solutions. R&D and procurement personnel who need electrode samples, process parameters, or volume quotations can visit the Huili Biotech official website to connect with our technical engineers and obtain complete test reports and customized solutions. Going forward, the company will continue to expand its precious-metal alloy electrode product line, upgrade its sputtering process for ultra-thin flexible PI substrates, and continuously optimize tiered procurement pricing to reduce BOM costs for device manufacturers.
