The present application discloses a method to produce fibers with different segments along the major axis. The different segments can be constituted of the same materials that entrap different objects (molecules, particles) or can be made of different materials. The different segments are made thanks to a junction and by alternating the dispensing of such materials using different inlet channels. This method allows the production of fibers that can be used as processed or after being further manipulated by other processes, as single devices or as building blocks to construct devices that are more complex. Fibers with different segments along the axis can be exploited for a wide range of applications as medical devices and/or as drug delivery system and/or as matrices to be used for acellular tissue regeneration and cellular tissue engineering/regenerative medicine strategies and/or as supports for imaging in high throughput screening.

Abrégé
The invention discloses a novel device for the formation of microcapsules based on micro-droplet generation inside silicone tubing, which is punctured with a blunt-ended syringe needle vertically (1). The device uses droplet generation by vertical injection of hydrophilic polymer/cell mixture into hydrophobic oil flow, which is horizontally maintained in the silicone tubing. The injection of polymer/cell mixture into a stream of mineral oil results in the generation of spherical droplet and in the formation of a water- in-oil emulsion due to the immiscibility of the two phases. Subsequently, the micro-droplets in oil phase are converted into stable microcapsules by gelation in a separate chamber which is loaded with ionic cross- linking solution at physiological ionic strength and pH. The utility of the microcapsules generated by the device of present invention is virtually unlimited in the fields of regenerative medicine, controlled delivery of growth factor or drug.
