it4ip custom membranes are currently in use in a wide range of markets. Thanks to an exquisite control over all its fundamental characteristics (i.e. pore size, distribution and shape), it4ip membranes stand out in applications where accuracy and reliability are critical.
Separation / Cancer diagnosis
By inserting a membrane whose pore size is carefully chosen, it is possible to selectively allow the desired molecules and proteins to cross the membrane while retaining specific cells, in this case circulating tumoral cells.
A similar approach has been used to screen rare cells and bacteria in biological samples. It has huge potential and very practical implications in the development of reliable and rapid diagnostic techniques or sterility assessment.
Flow control in biosensor
it4ip membranes display well controlled pore shape and dimensions. This feature allows accurate control and modelisation of the rheology at very small scale. As moreover, the length-scale of the pores tend to promote diffusive transport of matter, the membranes can be used to regulate the flux of particles reaching a chosen zone, often the sensitive zone of a sensor.
Templating : molded nanowires for applications in sensors and batteries
it4ip membranes have been used as molds to deposit a range of materials as metals and polymers. The membrane may then be dissolved to obtain nanowires or nanotubes. In the case of filling with translucent material, the optical properties of the membranes can also be significantly altered.
Enzymes and proteins immobilization on metal coated membrane
it4ip gold-coated membranes are the perfect tool to immobilize enzymes and proteines. Metal coatings on electrodes are also used as cathodes when electroplating nanowires and nanotubes. Even a very thin metal coating can significantly modify the optical properties of the membrane.
