Abstract
A microfluidic probe head is provided. The microfluidic probe head comprises a processing surface. The processing surface has a first and second aperture and a fluid injection channel, which leads to the first aperture. The microfluidic probe head comprises also a first fluid aspiration channel which leads to the second aperture. Thereby, the second aperture forms a slot in the processing surface. Furthermore, a microfluidic probe may be provided comprising the microfluidic probe head.
