Abstract
A microfluidic system comprises a first portion and a second portion. The first portion comprises a material which is able to change its volume when activated by an exciting factor, characterized by the fact that the first portion and the second portion define a zone which, when the first portion is not yet activated by the exciting factor, shows a first topography devoid of any fluidic pathway and which, after activation by the exciting factor, shows a second topography which is adapted to contain at least one fluidic pathway. The microfluidic system further comprises a tight cover surface situated above the first portion and the second portion.
Claims43
A microfluidic system comprising:
- a first portion, and
- a second portion,
- said first portion comprising a material which is able to change its volume when activated by an exciting factor, wherein said first portion and said second portion define a zone which, when said first portion is not yet activated by said exciting factor, the zone shows a first topography devoid of any fluidic pathway and which, after activation by said exciting factor, the zone shows a second topography which defines at least one fluidic pathway,
- said microfluidic system further comprising a tight cover surface situated above said first portion and said second portion, and
- wherein said first and second portions are deposited on a basis surface.
A microfluidic system comprising:
- a first portion, and
- a second portion,
- said first portion comprising a material which is able to change its volume when activated by an exciting factor, wherein said first portion and said second portion define a zone which, when said first portion is not yet activated by said exciting factor, the zone shows a first topography devoid of any fluidic pathway and which, after activation by said exciting factor, the zone shows a second topography which defines at least one fluidic pathway,
- said microfluidic system further comprising a tight cover surface situated above said first portion and said second portion, and
- wherein said material is expandable and is a mixture comprising beads made of a polymeric shell containing a liquid hydrocarbon.
