In this study, the application of amphipods in vivo assays was evaluated. The main aim of this work was to check the potential use of this model in biocompatibility assessments of metal-organic frameworks (MOFs). Hence, six different MOFs were synthesized and the in vitro and ex vivo cytotoxicity was first assessed using a colorimetric assay and a macrophage cell line. Obtained results were compared to validate the in vivo toxicity tests carried out using amphipods and increasing concentrations of the different MOFs. Amphipods do not require the need of ethics approval and also are less expensive to keep than conventional in vivo models, showing its potential as a fast and reliable platform in toxicity studies. The obtained results showed that the amphipods based-assay was simple, easy to replicate and yielded toxicity data corresponding to the type of MOFs tested. In addition, it was observed that only CIM-80(Al) and CIM-84(Zr) did not show any toxicity to the animals at the different tested concentrations. Therefore, the developed in vivo model could be applied as a high-throughput toxicity screening method to evaluate the toxicity of numerous materials, chemicals and therapeutic agents among others.

<p>The emergence of drug delivery using water stable metal-organic frameworks has elicited a lot of interest in their biocompatibility. However, few studies have been conducted on their stability in common buffers, cell media, and blood proteins. For these studies, single crystal ZIF-8 approximately 1 um in diameter were synthesized, incubated with common laboratory buffers, cell media, and serum, and then characterized by PXRD, IR, DLS, and SEM. Time-resolved SEM and PXRD demonstrate that buffers containing phosphate and bicarbonate alter the appearance and composition of ZIF-8. Further, blood proteins in serum dissolve ZIF-8, causing trapped biomolecules to escape. The study presented here suggests that ZIF-8 can undergo dramatic surface chemistry changes that may affect the interpretation of cellular uptake and cargo release data. On the other hand, it provides a rational explanation as to how ZIF-8 neatly dissolves <i>in vivo</i>. </p>

In the field of bioinorganic chemistry, porosity has been explored for the development of metal-organic frameworks (MOFs), innovative polymers, or networks composed of metal centers that stabilize organic molecules with high contact surface and well-defined crystalline structures. MOFs have also been investigated for drug therapies due to their high loading capacity, thermal stability, low electrical conductivity, biodegradability, biocompatibility, easy functionalization, and size considered adequate to control drug release in vivo. MOFs can be sensitive to variations in pH, magnetism, temperature, pressure, light, and humidity, making them desirable for vectorizing extended release systems. Among the most investigated pharmacological groups for association with MOFs are anti-inflammatory and antineoplasic drugs. Here the authors explore the recent advances of MOFs-based drug delivery systems, their current limitations, and discuss the evidences towards their potential clinical use.
