Force Spectroscopy
Force Spectroscopy is an advanced Atomic Force Microscopy (AFM) mode that measures tip-sample interactions to quantify nanoscale mechanical properties and molecular forces. This mode is indispensable for studying adhesion, elasticity, and intermolecular interactions in materials science, life sciences, and nanotechnology.
Manufacturer
CSI
CSInstruments is a French scientific equipment manufacturer specialised in the conception of Atomic Force Microscope and options designed for existing AFM (Nano-Observer AFM, Resiscope™, High Voltage Amplifier, Magnetic modules). The product range proposed by CSInstruments is designed and manufactured to help the scientific community to achieve nanometre performances that meet the research needs and requirements for actual and future nanoscience applications.
CSInstruments was founded by a team of experts working in AFM field for more than 20 years, starting as pioneer with some historical manufacturers. CSInstruments activity is also based on a qualified and dynamic team, experienced in the fields of mechanics, electronics and data processing. This expertise ensures innovation and performance in the production of AFM and achieves an excellent price/performance ratio!
Key Features
- Quantitative Force Measurements: Accurately determine adhesion, stiffness, and molecular interaction forces
- Wide Force Range: From picoNewtons to microNewtons, accommodating diverse applications
- High Sensitivity: Detect subtle changes in tip-sample interactions with picoNewton precision
- Versatility: Applicable in ambient, liquid, and controlled environments
- Real-Time Analysis: Obtain immediate feedback on force-distance relationships
How does Force Spectroscopy work?
Force Spectroscopy involves measuring the deflection of an AFM probe as it approaches and retracts from a sample surface. The resulting force-distance curves reveal key mechanical and molecular properties, such as adhesion forces, Young’s modulus, and energy dissipation.
