nanoimmunotech is a spanish company in the Nanobiotechnology sector, founded in August 2009 and recognized as EIBT (Technologically Innovative Company).

nanoimmunotech is your benchmark and reference partner within the Nanobiotechnology world. We offer you a complete range of products, services and tailor-made projects to help you from the design of your nanoparticles, nanomaterials or complex nanosystems by means of bioconjugation, to check the properties of your products, the reproducibility of their production or their biological effects, among others.

The company has highly qualified and internationally recognized human resources, state-of-the-art laboratory capabilities, standardized protocols and finally, the know how to perform proper supervision, advice and validation of different nanosystems, as a first step to the previous use of nanoparticles in biotechnological applications for different sectors (biomedical, pharmaceutics, cosmetics, veterinary, agro-food, environmental, etc.).

The nanoimmunotech’s business model is flexible and we have experience in participating in research or on demand projects, licensing, customer-supplier relationships, etc.


The company is based on the following business areas:

  1. The core business of nanoimmunotech is the product portfolio based on the nitzipper® technology, an innovative Bioconjugation solution, that allows to quickly, easily, and effectively combine many different types of micro/nanostructures, biomolecules, dyes, linkers, drugs and other molecules, in practically any combination in an oriented way and without modifying their properties.
  2. 2. Services of Biological (in vivo and in vitro) and Physico-chemical characterization of nanoparticles and products using nanotechnology, respectively called nitbiosafe and nitcharacter, giving support to very different customers (pharmaceutics, cosmetics, diagnostics, agrofood market, etc.) so they can design better and safer products.

Products and services


nitzipper® is an innovative Bioconjugation solution that allows you to create millions of combinations between molecules and/or structures.

nitzipper® is a playground that helps you build your own micro / nanostructures as you would do with puzzles, where the pieces are the micro / nanostructures and molecules that you can join together in infinite ways.

nitzipper® is a revolutionary technology that makes it possible to quickly and easily join all these pieces (micro / nanostructures and biomolecules).

With nitzipper® we convert for you any molecule or structure into a Plug&Play element that can be bond to any other element endowed with the nitzipper® technology.


nitcharacter is the quality brand offered worldwide by nanoimmunotech SL, gathering all the necessary services for consultancy and physico-chemical characterization of particles (micro/nanoparticles).

nitcharacter provides consultancy and high precision testing for solutions based on particle analysis and size distribution, morphological studies, surface charge determination, chemical / structural analysis, determination of particles intrinsic properties, etc...


nitbiosafe es la marca de calidad bajo la que se agrupan todos los servicios de caracterización biológica in vitro e in vivo de materiales nanoestructurados, así como el asesoramiento sobre los mismos que nanoimmunotech SL ofrece a nivel mundial.

Con nitbiosafe podrá realizar una batería completa de ensayos in vitro para la valoración de sus nanopartículas o nanoestructuras, determinando su: toxicidad, biocompatibilidad (hemo y citocompatibilidad), inmunogenicidad, biodistribución, esterilidad, etc.

Adicionalmente, el uso de modelos animales se hace imprescindible para la confirmación de los ensayos in vitro, tanto los de toxicidad celular como de inmunogenicidad.

Es por esta razón que nanoimmunotech SL pone a su disposición un animalario y las más actuales pruebas in vivo, para que usted pueda testar sus productos.
