Las Palmeras, 4, 18100 Armilla, Spain ABSTRACT: New biomimetic magnetite nanoparticles (hereafter BMNPs) with sizes larger than most common superparamagnetic nanoparticles were produced in the presence of the recombinant MamC protein from Magnetococcus marinus MC-1 and functionalized with doxorubicin (DOXO) intended as potential drug nanocarriers. Unlike inorganic magnetite nanoparticles, in BMNPs the MamC protein controls their size and morphology, providing them with magnetic properties consistent with a large magnetic moment per particle; moreover, it provides the nanoparticles with novel surface properties. BMNPs display the isoelectric point at pH 4.4, being strongly negatively charged at physiological pH (pH 7.4). This allows both (i) their functionalization with DOXO, which is positively charged at pH 7.4, and (ii) the stability of the DOXO−surface bond and DOXO release to be pH dependent and governed by electrostatic interactions. DOXO adsorption follows a Langmuir−Freundlich model, and the coupling of DOXO to BMNPs (binary biomimetic nanoparticles) is very stable at physiological pH (maximum release of 5% of the drug adsorbed). Conversely, when pH decreases, these electrostatic interactions weaken, and at pH 5, DOXO is released up to ∼35% of the amount initially adsorbed. The DOXO−BMNPs display cytotoxicity on the GTL-16 human gastric carcinoma cell line in a dose-dependent manner, reaching about ∼70% of mortality at the maximum amount tested, while the nonloaded BMNPs are fully cytocompatible. The present data suggest that BMNPs could be useful as potential drug nanocarriers with a drug adsorptionrelease governed by changes in local pH values.

INTRODUCTION
derived from the fact that conventional synthesis of magnetic nanostructured materials often requires toxic reagents.1 Moreover, the superparamagnetic nanoparticles resulting from these synthetic procedures are relatively small ( 1000 nm (Figure 7) and, therefore, they could not undergo EPR effect. However, there is still a population with a size ≤150 nm (dots within the colored area in the figure) that could reach the H

tumor site by EPR effect.48 Nevertheless, EPR effect by itself might not be enough in this case to ensure a correct targeting of the tumor site, and other ways of cell targeting such as additional coupling of the BMNPs with monoclonal antibodies combined with active guidance of the BMNPs to the target site by means of the application of an external magnetic field should be explored in the future to increase the efficiency of the targeting. The slowest sedimentation occurred in the samples containing nonloaded BMNPs (0.0192 mm/s), and the fastest sedimentation occurred in DOXO−BMNPs, 0.038 mm/s. These results are in accordance with the data of hydrodynamic
radius, in which it was observed that the latter binary biomimetic nanoparticles exhibited the highest percentage of aggregates. Colloidal stability of these binary nanoparticles, nevertheless, should be improved in the future. As a summary, there are a number of findings that make BMNPs unique and good candidates as potential drug nanocarriers for targeted drug delivery, although colloidal stability still needs to be improved. The advantages of the biomimetic nanoparticles of the present study are: (1) nonloaded BMNPs are cytocompatible, but they become cytotoxic when coupled with DOXO; (2) they exhibit a large magnetic moment per particle; (3) DOXO adsorption and I

release can be controlled efficiently by changes in pH, like those that naturally occur when entering from the blood stream to the tumor tissues; (4) MamC provides the surface of the BMNPs with functional groups that allow coupling with other molecules; and (5) the DOXO−BMNPs nanoassembly is quite stable at physiological pH values.

CONCLUSIONS The potential role of BMNPs produced in the presence of MamC as drug nanocarriers has been assessed for the first time. The BMNPs produced in the present study are pHsensitive nanocarriers in which DOXO adsorption is mostly driven by electrostatic interactions between positively charged DOXO amino groups and negatively charged acidic residues of the MamC that is attached to the surface of the crystal. By contrast, desorption of DOXO from the DOXO−BMNPs nanoassembly is achieved by weakening this bond as pH decreases and approaches the iep of the BMNPs (iep 4.4). The adsorption process follows a Langmuir−Freundlich model, which shows that the surface of the magnetite is energetically heterogeneous and displays positive cooperativity. The BMNPs coupled with DOXO (DOXO−BMNPs) are stable at physiological pH with maximum releases of 5% of the initial DOXO adsorbed, while the desorption process is efficient since about 35% of the adsorbed drug was released in just 4 h at pH 5. Moreover, these DOXO−BMNPs nanoassemblies are cytotoxic for the GTL-16 carcinoma cell line, in which they induced more than 70% mortality. This toxicity was dependent on the DOXO adsorbed to the BMNPs since nonfunctionalized nanoparticles were highly cytocompatible and hemocompatible when in the presence of red blood cells. All together, these data indicate that BMNPs are unique magnetite nanoparticles with novel properties acquired thanks to their interaction with the protein MamC and, therefore, their potential as nanocarriers should be further explored in future studies.
