Scientific Leaders of the project: Javier García, José Luis Pedraz, Simó Schwartz & Ramón Mangues. One of the causes that increase the time to market of nanotherapeuticsis its preclinical validation. The standard protocols for more traditional drugs are not applicable for nanomedicines. NANBIOSISoffers a preclinical study plan tailored to meet the demands of each nanomedicine product, developed in collaboration with the user and starting from a set of basic analytical tests to more sophisticated experiments. We offer a complete In vitro Characterization. e.g., immunology, cytotoxicity, hematology, oxidative stress, etc, and more adapted to the different products by using the most sophisticated equipment and taking advantage of the expertise of scientist internationally recognized in the matter.
