AFM in liquid
Imaging biological and polymer samples in liquid
Cells, biomolecules, polymers and electrode surfaces often have to be measured in liquid, in conditions close to their real environment. The EZ Liquids accessory turns the Nano-Observer II and Nano-Observer AFMs into liquid AFMs:
- Contact and resonant modes in liquid — a dedicated liquid cell and tip holder.
- No re-alignment — laser angle compensation keeps the laser on the photodiode when the cell is filled.
- Long, stable sessions — the cell limits evaporation, for long resonant-mode imaging with little drift.
- Biology — living cells, biomolecules and force spectroscopy in physiological conditions; bacterial structures imaged in liquid on a 4.5 µm scan, DNA on mica and blood cells.
- Materials and electrochemistry — surfaces in liquid media, corrosion in real time and electrochemical AFM with an optional bi-potentiostat connection.
FAQ
Frequently Asked Questions
Which AFM can image biological samples in liquid?
The Nano-Observer AFMs with the EZ Liquids accessory image cells, biomolecules and bacteria in liquid, in contact and resonant modes, with laser angle compensation and reduced evaporation for long, stable sessions.
Which AFM modes work in liquid?
Contact mode and resonant (tapping) mode, as well as force spectroscopy on biological samples and electrochemical AFM with an optional bi-potentiostat.
Can polymer or material surfaces be measured in liquid?
Yes. The liquid cell is used to analyse surfaces in liquid media, to follow corrosion processes in real time and to study liquid–solid interfaces.
