We are Doxa

In last 15 years, Doxa® has developed an outstanding know-how and expertise in the theoretical basics and applications of Microfluidics Techniques, mainly Coaxial Electrospraying/ Electrospinning and Coaxial CoFlowing which are the core of Doxa® and target both fundamental research as well as commercial products.

The use of the mentioned techniques can lead either to the formation of functional core-shell nanoparticles and nanofibers, which are crucial for a variety of industrial and research applications such as food/agro technology, drug protection/delivery, pharma/veterinary, cosmetics, nanocomposites, catalysis and nanosensors or chemicals among others.

Doxa® delivers to Worldwide Companies and Universities a wide range of equipment and services that may help to increase the results of their research or develop new and innovative products.


CoFlowing tech.

CoFlowing is a technique that can achieve mono disperse microspheres in the range of 1-50 microns; the production of microcapsules or microfibers have a size significantly lower than that of the fluid injected hole diameters can be obtained.

Electrospinning & Electrospraying Tech.

This technique is the best choice to deal with spherical or fibered micro-nanoparticles (Simple/hollow/core-shell) having high loading efficiency whose shows a range of release triggers and is compatible with a wide range oc active ingredients.


Our experience for more than 15 years could help you to design the process for the production of micro-nano particles/fibers using some of the most innovative techniques.

Coaxial Technology

Preparation of nanofibers in a core-sheath configuration, using two dissimilar materials, via a novel technique of co-axial electrospinning has presented unusual potential for use in many novel applications. The studies have addressed issues related to the technology involved and examined the suitability of the technique for producing unique nanoscale morphologies involving variety of materials. In this first major review of co-axial electrospinning, we provide details of the manufacturing and material factors affecting the process, the conditions needed for preparing desired uniform morphologies, and the different types of structures that have been successfully produced.
