Product Description

Application:Diamond electrode is grown on silicon substrate for electrochemical disinfection.

eg:

1. Disinfection of Medical devices :

- Real-time electrolytic water cleaning system for endoscopes and surgical instruments.

- Anti-bacterial coating on the surface of the implant.

2. Water Treatment System :

- Terminal disinfection module for drinking water/sewage plants.

- Ship ballast water treatment (avoidance of biological invasion).

3. Food Industry :

- Sterilization of fruits and vegetables and packaging materials on the production line.

- Chemical free sterilization of dairy products before filling.

4. Portable Devices :

- Field water purifier, generate disinfecting water through USB power supply.


Why choose silicon:

Silicon (100) wafers are ideal substrate materials due to their high purity, flat surface and semiconductor properties, providing mechanical support and thermal conductivity.


processing step: surface cleaning-Nanocrystalline seed layer- Diamond film growth (CVD process)- Electrode conducting structure design- Electrolysis produces active substances


Advantage:

1.  Efficient disinfection :

The oxidation potential of hydroxyl radical (•OH) generated by BDD electrode reached 2.8V, which was much higher than that of traditional chlorine disinfection (1.36V), and could quickly inactivate drug-resistant bacteria.
2. No secondary pollution :
Does not rely on chemical agents, only water and electricity, the product is H₂O and O₂, environmental protection and safety.
3. Long life and stability:
Diamond is chemically inert, resistant to corrosion (especially in acidic/high salt environments), and has an electrode life of thousands of hours.
4. Silicon-based integration advantages:
- The high thermal conductivity of silicon can quickly dissipate heat and avoid local overheating of the electrode.
- Compatible with microelectronic processing, suitable for miniaturized equipment (e.g. lab-on-a-chip)
