Cellena® by Biomedal

Cellena® is a bioencapsulation portable platform able to encapsulate high molecular weight compounds, microorganisms and cells in homogeneus particles of predictable and controlable size. Designed by Ingeniatrics, it has been specifically developed for biotechnological research. Its performance is based on Flow Focusing® technology. By means of this technology, the elements to be encapsulated are immobilized within a semipermeable membrane that protects them from mechanical stress and the host immune system, allowing the bidirectional diffusion of nutrients, oxygen and secretory products including waste.

Portable Cellena® is a User-friendly equipment that allows to obtain both, particles much smaller than any other microencapsulation technology, with a precise control of the desired particle size. Despite its small size the portable equipment Cellena® can be used to obtain from small samples to large volumes, using a great variety of polymers.

Cellena® Flow Focusing® technology offers a unique capacity of drops, particles and capsules generation in a non aggressive way, getting controllable homogeneous sizes and diameters.
Flow Focusing® technology was discovered in 1994 by Professor Alfonso Gañán-Calvo’s research team, this technology can be used to design and produce microparticles of a chosen size, structure and composition. Is a microfluidic technology capable of monodispersed droplet formation and manipulation, based on the production of capillary microjets that are "targeted" towards an orifice.
Flow Focusing® is a pneumatic atomization technology in which the aerodynamic effect of two immiscible fluids allows to control the size of the exerted jet making it much smaller than any other pneumatic technology. Once the jet is produced, it breaks up into very equal and similar droplets. These droplets could be maintained as aerosols or get solidified yielding solid particles or capsules.
