Estimating the term…
The invention relates to a process for preparation of an unpassivated cantilever comprising the steps of: 1) providing a silicon cantilever sensor having two sides; 2) coating one side of the cantilever with at least a gold layer; and 3) functionalizing both sides of the cantilever with a self-assembled monolayer (SAM) of a probe molecule by incubating the cantilever in a solution having a concentration of the probe molecule of between 1 to 1000 μM. The invention also relates to an unpassivated cantilever sensor comprising a silicon layer coated on one side with a coating comprising Au and being uncoated or unpassivated on the opposite side, wherein the Au coated surface comprises a self-assembled monolayer of a probe molecule and wherein the surface area occupied per probe molecule is in the range 0.4-1.5 nm2.
A process for preparation of an unpassivated cantilever, comprising the steps of:
An unpassivated cantilever sensor comprising a range of material such as polyamide or silicon layer coated on one side with a coating comprising Au and being uncoated or unpassivated on the opposite side, wherein the Au coated surface comprises a self-assembled monolayer of a probe molecule and wherein the surface area occupied per probe molecule ranges from about 0.4 to about 1.5 nm2.
