Colloidal probes are used to study interaction forces between two surfaces and to quantify them (force spectroscopy). It requires an AFM tip with well defined geometry to estimate contact area for force measurements. AppNano offers colloidal probes, where a well defined particle is mounted on a tip-less cantilever in clean and consistent manner for reproducible results.
How to select your Colloidal Probe :
1) Please select your tipless Cantilever from our vast range of tipless probes using the product search engine.
2) Select the type and diameter of colloid :
|Sio||A - 5µm to 9µm|
|BSG||B – 10µm to 14µm|
|PS||C – 15µm to 19µm|
|D – 20µm or more|
3) Select the coating options:
|Reflex side||None, Al, Au|
|Tip side:||None, Au|
