A scanning probe microscopy head may include a base portion, cantilevers coupled to the base portion, and at least one tip coupled to each of the cantilevers. The invention also features methods of producing an active fraction from an extract of Cimicifuga. The binding resins are thermoplastic polymeric materials and the step of bringing the binding resins to the fluid phase takes place by melting of the binding resins. When the locking pin is removed, the worm drive controls the swiveling of the horse head member in either direction towards either side of the working beam.
