    Biomedicine is an industry related to national economy and people's livelihood, whose development plays an important role in promoting social stability. Countries around the world have always attached great importance to the development of biomedical industry, at the same time, various policies and measures have been adopted to vigorously promote the development of the biomedical industry. Thus, it can be seen that biomedicine plays an essential role in the development of social economy. Recent decades have witnessed a surge of explorations of biomedical applications in drugs delivery, bioimaging, therapy (chemotherapy, genetherapy, immunotherapy photodynamic therapy and photothermal therapy), tissue engineering and others. Multifarious materials have been widely developed to achieve these objectives, including organic (liposomes, polymer, dendrimers, etc.), inorganic (metals, metallic oxides, carbon, mesoporous silica, etc.) However, there are still more materials limited due to their unsatisfactory efficiency or safety.


    Application of MOFs and COFs in Biomedicine

    Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) have showed potential applications in biomedical field, which can be used in therapy, drugs delivery, biomedical imaging and others. The reasons can be described as follows: the structural periodicity, high porosity, and internal channels and pores of MOFs and COFs are beneficial to achieving high payloads and facile transport of drugs. And the versatility structure of MOFs and COFs enables it to deliver and release drugs or therapeutic agents in a controlled manner, achieving efficient therapy of disease and cancer and also providing effective therapeutic platforms in synergistic anticancer therapy[1]. To date, numerous MOFs and COFs have been applied in biomedicine fields.


    Advantages of Using MOFs and COFs

    Compared with the traditional materials for biomedical applications, MOFs and COFs demonstrate the following advantages[2]:

    • Thousands of MOFs and COFs provide a library of versatile porous materials for various bio-related applications;
    • The stable but degradable structures guarantee the reuse and on-demand degradation;
    • The high specific surface areas and porsities facilitate the efficient encaspsulation of cargos, ranging from small molecules to biomacromolecules.
    • The good biocompatibility of MOFs and COFs ensure the biosecurity for in vivo applications.

    Alfa Chemistry can provide the high-quality MOFs and COFs which can be mainly used in the following biomedical fields:
