摘要:
The invention relates to a method and a device which serves for moving and dosing amounts of liquid on a microscopic scale with a volume of especially 10−12 to 10−6 liters by means of an inhomogeneous electric field using a support having an ultraphobic surface.
摘要:
The invention relates to a structured surface with ultraphobic properties. Said surface as a surface topography in which the value of the integral of a function S: S(log f)=a(f)·f, which gives a relationship between the spatial frequencies f of the individual Fourier components and their amplitudes a(f) is at least 0.5 between the integration limits log (f1/μm−1)=−3 and log (f2/μm−1)=3. The surface consists of a hydrophobic or oleophobic material or is coated with a hydrophobic or oleophobic material.
