ClexBio Logo
engineering human tissue implants


ClexBio is a biotech company creating breakthrough solutions for tissue engineering and single-cell techniques by combining advanced microfluidics with our proprietary hydrogel technology CLEX.

The CLEX technology allows hydrogel formation with, both, precise control and exceptional biocompatibility. This enables us to use microfluidic devices to form hydrogel microstructures containing delicate biological cargo such as living cells.


Cell icon


The CLEX mechanism is highly compatible with delicate biological systems such as living human cells.

Microfluidics icon


Precise control over the gelation kinetics allows the use of advanced microfluidic devices.

Plug&play icon


The low complexity of the CLEX method allows for plug & play operation with existing hardware.

Scalability icon


The simple chemistry is based on readily available raw materials and can be scaled from µg to kg.

Versatility icon


Compatibility with a wide variety of polymers allows diverse applications from food to cosmetics to medicine.


The CLEX technology is the results of several years of research at NTNU, Harvard University, and EPFL. The science behind CLEX has been published in internationally recognized scientific journals.
