Scheme of an AFM probe (AFM Tip)<\/p><\/div>\n<\/div>\n

AFM probes for atomic force microscopy can be chemically, biologically and physically modified by us. Chemically and biologically modified AFM probes can be used to obtain additional information such as the chemical composition of the surface in addition to the usual information provided by an AFM. This is called Chemical Force Microscopy (CFM<\/a>).<\/p>\n

You can select the appropriate AFM probes from our wide product range, depending on the chemical or biological composition of the hydrophilic or hydrophobic surface to be examined.<\/p>\n

If required, we are happy to advise and support you in the selection of the suitable AFM tip. We produce the customer-specific modified AFM probes according to your individual wishes. Please contact us directly under info@nanocraft.de<\/a>.<\/p>\n

The minimum order quantity is 5 probes per modification. Chemically sensitive electrodes are supplied in gel packs in air or inert gas or in a special holder in ethanol. Thus the shelf life of the chemically modified electrodes is several months if stored carefully.<\/p>\n
