Electrochemistry
BioNavis instruments can be equipped with electrochemistry modules, enabling simultaneous electrochemical measurements alongside either Multi-Parametric Surface Plasmon Resonance (MP-SPR) or Quartz Crystal Microbalance with Dissipation (QCMD) on the same sensor slide.
Electrochemistry with MP-SPR
Our highly sensitive MP-SPR instruments can be combined with various electrochemical techniques to simultaneously collect both optical and electrochemical real-time data from the same sensor surface. Multiple electrochemical methods, such as potentiometric, amperometric, and impedance spectroscopy, can be applied. A potentiostat can induce surface reactions (e.g., electrochemical switching).
Equip your MP-SPR with an easily changeable kinetic electrochemistry flow cell (NEW) or electrochemistry cuvette for static measurements!
Electrochemical measurements with MP-SPR
- Develop electrochemical sensors on one device (e.g., real-time monitoring of refractive index changes due to redox reactions)
- Measure the thickness and surface coverage during electrochemical metal deposition
- Quantify catalytic bioreactions
- Measure electro-switchable reactions and functional biomaterials
- Promote potential-enhanced surface functionalization
- Perform real-time measurements of conformational changes

Electrochemistry with QCMD
Quartz Crystal Microbalance with Dissipation Monitoring (QCMD) is widely utilized in electrochemical studies to investigate surface interactions and thin-film properties at the nanoscale. QCMD measures both mass changes and viscoelastic properties on electrode surfaces by monitoring the frequency and dissipation shifts of a quartz crystal resonator. By coupling QCMD with electrochemical methods like cyclic voltammetry or chronoamperometry, one can gain deeper insights into processes such as electrodeposition, corrosion, adsorption, and interfacial dynamics in real-time.
Electrochemical measurements with QCMD
- Measure ion adsorption, intercalation/deintercalation, and metal film deposition on electrodes.
- Monitor surface changes under applied potentials, including shifts in material rigidity or detachment
- Track protein adsorption on electrodes
- Monitor catalytic reactions
- Monitor SEI formation in lithium-ion batteries and supercapacitors during charge-discharge cycles
- Measure the formation of protective oxide layers on metals
- Track electrochemical polymerization and degradation of conductive polymers
