Microstructure, for minimal- and non-invasive diagnostics, analysis and therapy, has base plate whose surface is sub-divided into zones with different capillary characteristics

摘要

A medical diagnostics assembly manipulates nano-quantities of fluid. The assembly has a base plate (1) whose surface is sub-divided into zones (6, 7) whose different surface structures have different capillary characteristics. One or more first zones have structures (6a - 6e) with regular micro- or nano-structures. The base plate and structured zones are formed from a single piece of material. Also claimed is a process to fabricate the medical diagnostics assembly by machining, laser beam cutting, exposure to an ion beam or micro injection-molding. The base plate and other structures are made from a single piece of material e.g. plastic, glass or silicon.
