Metal—organic frameworks MOFs and zeolitic imidazolate frameworks ZIFs are promising porous materials for adsorption and storage of greenhouse gases, especially CO 2.

Zif 8

Beyond being an excellent protective material for bioentities, zeolitic imidazolate frameworks ZIF-8 have advanced several applications, including biomedical applications. The straightforward synthesis of ZIF-8 at mild conditions improved the biomineralization of several biomolecules, e. Bioinspiration of ZIF-8 enhanced and improved the material's applications for biomedicine. This review article summarized the recent achievements of ZIF-8 for biomedical applications such as cancer therapy, antimicrobial, biosensing, and biocatalysis. ZIF8-based materials advanced cancer therapy via drug delivery of chemotherapeutic drugs, photothermal therapy PTT , photodynamic therapy PDT , chemodynamic therapy CDT , gene therapy, and starvation therapy. Antibacterial agent encapsulated ZIF-8 exhibited superior biological activity compared to the free antibacterial agents. ZIF-8 based materials enhanced the selectivity and sensitivity for analytes' biosensing, ensuring their potential for electronic devices. Biocatalysis of enzyme encapsulated ZIF-8 offered high catalytic performance with robust properties for recycling. ZIF-8 acts as a protective host for enzymes, proteins, and drugs from degradation induced due to temperature, solvents, and proteolytic agents. The first part of the review discussed the structure, chemistry, and bioinspiration of ZIF

USA— Supplementary Fig, zif 8. Sonochemical synthesiswhich allows nucleation reactions to proceed rapidly through acoustic generation of localized heat and pressure, has been explored as a way to shorten synthesis times.

The production of MOFs at large scale in a sustainable way is key if these materials are to be exploited for their promised widespread application. Much of the published literature has focused on demonstrations of preparation routes using difficult or expensive methodologies to scale.

The use of nanomaterials for the controlled release of drugs aims to enhance their effectiveness, especially when poorly soluble in water, and achieve their rapid, localized, and effective administration. The present study focuses on the use of a Zeolitic Imidazolate Framework-8 ZIF-8 as vehicle for the transport and controlled release of the antibiotic ciprofloxacin CIP as model due to its favorable physicochemical characteristics. The objective is to synthesize the ZIF-8 material loaded with CIP through encapsulation for subsequent release of the drug in neutral and acid physiological media.

Bazzi L. Deng C. Guo Z. Xiong J. The glassy form would also offer unique opportunities for easy processability and mass production. Musselman, Microporous and Mesoporous Materials, , , The product was collected by filtration and the solid residue washed three times with water. Wang N. Consequently, at this pressure, the CO 2 uptake has not reached the maximum even though the fluidity of CO 2 is significantly enhanced by heating. Hu and H. While a study on the effect of scale on these materials is a key, and currently underexplored, area of study it is outside the scope of this work. Some of the samples present either only SAED analysis or Fourier analysis, the reason for that is the difficulty in measurement due to samples instability under the beam. Solvent-free methods, such as ball-milling or chemical vapor deposition , have also been described to produce high-quality ZIF

As a new kind of porous material, zeolitic imidazolate frameworks ZIF-8 are built from zinc ions and 2-methylimidazolate and possess unique merits including high porosity, good structural regularity and tunability, adjustable surface functionality and intrinsic pH induced biodegradability. These advantages endow ZIF-8 with multiple functionalities and stimuli-responsive controlled release of loaded payloads by endogenous or exogenous means. In this review, we will summarize the recent advancement of ZIF-8 as nanocarriers for the loading of various molecules including chemotherapeutic drugs, photosensitizers, photothermal agents, and proteins to fabricate multifunctional nanocomposites for synergistic cancer therapy.
