“…Intrinsically, unstable agents can be protected against processing conditions and hard-working environment and ultimately released with a controlled pattern in a desirable environment [26][27][28]. Many studies have shown that nano-layered materials can encapsulate DNA [29,30], nucleotides [31,32], drugs [33,34], proteins [35], and even viruses [36]. These nano-hybrid systems are designed to enhance the efficient delivery to cells and the effectiveness of biochemical molecules [37][38][39].…”

Clay nanoparticles are among the most applicable and cost-affordable materials, all of which have a variety of applications in case of medical science. In this chapter, key characteristics of the clay nanoparticles along with their major groups, structure, morphology, and physicochemical properties were evaluated. Thereafter, the applications of clay nanoparticles in the field of nanocomposite, polymeric matrices, and medicine were investigated, while specimen production procedures were also reviewed. The main focus of this chapter is to investigate the applications of clay nanoparticles in bio-and medical science. In fact, organically modified clay nanoparticles (organoclays) are an attractive class of hybrid organic-inorganic nanomaterials with potential applications in case of polymer nanocomposites, rheological properties modification, and drug delivery carrier.

A bionanohybrid based on ascorbic acid-intercalated layered double hydroxides (LDHs) was synthesized using a facile and novel mechanochemical grinding technique, and its efficacy as an edible food coating is reported. Ascorbic acidintercalated Mg-Al-LDHs (AA-LDHs) are synthesized using a green water-assisted grinding approach. The successful synthesis of the mechanochemically ground AA-LDHs was confirmed by the shifts observed in the basal peaks of the LDHs based on a powder X-ray diffraction, changes in the positions of vibrational frequencies of ascorbic acid based on Fourier Transform Infrared Spectroscopy, and significant changes in the intensity and peak positions of the core−shell bands based on X-ray photoelectron spectroscopy. The resulting nanohybrid further demonstrates thermal stability in thermogravimetric and derivative thermogravimetric analysis. Transmission electron microscopy images of the mechanochemically synthesized AA-LDHs reveal a plate-like morphology, which is a characteristic of the hydrotalcite-like structure. In a novel application, an edible coating was prepared by blending the AA-LDHs into a biocompatible alginate matrix, and the coating was developed on freshly plucked strawberries using the dip-coating method. In order to evaluate the efficacy of the coating, the total phenolic content, pH, microbial growth, weight loss, titratable acidity, and ascorbic acid content were monitored in the coated and uncoated fruits for a period of 18 days. The results reveal that the shelf life of strawberries increases from 9 days to 15 days for the nanohybrid coated fruits, suggesting the potential food preservation applications of the nanohybrid.
