IDEs for Molecular Detection and Biosensors
In biosensors, your electrode surface is where biology meets electronics. If your IDE isn’t stable, clean, and customizable, your data is unreliable—no matter how great your molecule is.
At Schnaiffer, we design Interdigitated Electrodes (IDEs) specifically for biosensing.
From glucose sensors to DNA hybridization chips, we help research teams and biotech innovators build sensors that are reproducible, scalable, and biologically compatible.
What Makes Our IDEs Biosensor-Ready?
Schnaiffer IDEs are engineered specifically for the needs of biosensing—where signal clarity, surface chemistry, and biocompatibility are non-negotiable.
Our electrodes are optimized to interface seamlessly with biomolecules, microfluidics, and electrochemical detection systems.
Whether you're detecting glucose, DNA, pathogens, or proteins—our IDEs offer the performance, reliability, and flexibility biosensors demand.
Applications
- Glucose Sensing: Enzyme-linked (GOD, GOx) electrochemical systems
- DNA Hybridization: Label-free impedance shift detection
- Pathogen Sensors: Real-time virus/bacteria tracking with aptamers
- pH & Ion Sensors: Capacitive change-based probes
- Neurochemical Probes: Dopamine, serotonin, adrenaline sensors
Our Fabrication Process
We follow microfabrication process to deliver high-precision IDEs on different substrates. Each electrode is tailored for biosensors, gas sensing, and microelectronic applications.
Key steps include:
- Photolithography: Defines electrode geometry with micron-level precision.
- Thin-Film Deposition: Gold, platinum, silver, or carbon films via sputtering or evaporation.
- Lift-Off or Etching: Clean removal of excess material for sharp electrode patterns.
Our process ensures reproducibility, customizability, and high signal fidelity in every batch.
