“…In addition, after alginate coating, calcium deposition increased in both 7 and 14 days. Similarly, various studies [68][69][70][71][72][73][74][75][76][77][78][79][80] reported that alginate coating increased calcium deposition and new bone formation. For example, Jang et al [69] demonstrated the great calcium deposition results on the PCL scaffold with alginate coating.…”

Despite the significant advancement in bone tissue engineering, it is still challenging to find a desired scaffold with suitable mechanical and biological properties, efficient bone formation in the defect area, and antibacterial resistivity. In this study, the zeolite (ZSM-5) scaffold was developed using the space holder method, and a novel vancomycin-loaded alginate coating was developed on it to promote their characteristics. Our results demonstrated the importance of alginate coating on the microstructure, mechanical, and cellular properties of the ZSM-5 scaffold. For instance, a three-fold increase in the compressive strength of coated scaffolds was observed compared to the uncoated ZSM-5. After the incorporation of vancomycin into the alginate coating, the scaffold revealed significant antibacterial activity against Staphylococcus aureus (S. aureus). The inhibition zone increased to 35 mm. Resets also demonstrated 74 ± 2.5% porosity, 4.3 ± 0.07 MPa strength in compressive conditions, acceptable cellular properties (72.3 ± 0.2 (%control) cell viability) after 7 days, good cell attachment, and calcium deposition. Overall, the results revealed that this scaffold could be a great candidate for bone tissue engineering.

“…This was probably due to a higher partition coefficient for zinc than for cadmium and a stronger binding of the zeolite to zinc. In contrast, Senila et al [ 180 ] showed that clinoptilolite, in addition to being an adsorbent of contaminants, can also act as a carrier for biofilm formation and microbial growth involved in biological wastewater treatment, which has a beneficial effect on the overall process. The usefulness of silver-modified clinoptilolite in immobilizing Cr(VI) ions from model wastewater was demonstrated by Panayotova [ 181 ].…”

Zeolites, a group of minerals with unique properties, have been known for more than 250 years. However, it was the development of methods for hydrothermal synthesis of zeolites and their large-scale industrial applications (oil processing, agriculture, production of detergents and building materials, water treatment processes, etc.) that made them one of the most important materials of the 20th century, with great practical and research significance. The orderly, homogeneous crystalline and porous structure of zeolites, their susceptibility to various modifications, and their useful physicochemical properties contribute to the continuous expansion of their practical applications in both large-volume processes (ion exchange, adsorption, separation of mixture components, catalysis) and specialized ones (sensors). The following review of the knowledge available in the literature on zeolites aims to present the most important information on the properties, synthesis methods, and selected applications of this group of aluminosilicates. Special attention is given to the use of zeolites in agriculture and environmental protection.

“…Detoxifying Effects of Zeolite-Ammonium, Nitrates, Nitrites, Mycotoxins, Pesticides, Synthetic Neurotoxins, and Radionuclides Diets rich in proteins and with reduced carbohydrate content modify the colonic microbiome, favoring a potentially pathogenic and pro-inflammatory microbiota profile, decreasing short-chain fatty acid production, and increasing ammonia and hydrogen sulphide concentrations, the latter, reflecting excessive protein fermentation, being implicated in the pathogenesis of irritable bowel syndrome, ulcerative colitis, and colorectal carcinogenesis as well [92]. Zeolite has a proven very high affinity toward ammonium (the selectivity of ion exchange on natural clinoptilolite has been reported in an order of K + > NH 4 + > Na + > Ca 2+ > Mg 2+ (e.g., [93,94])) and has long been used to efficiently remove ammonium from fresh and waste water [55,[95][96][97][98] and also shows favorable effects in humans when used as a supplement in the protein-rich diet of endurance-trained individuals [91]. Except for ammonium (NH 4 + ), zeolite has shown high removal efficiency for nitrates (NO 3 − ) and nitrites (NO 2 − ) as well [55,99].…”

Neurodegenerative diseases (NDs), characterized by progressive degeneration and death of neurons, are strongly related to aging, and the number of people with NDs will continue to rise. Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the most common NDs, and the current treatments offer no cure. A growing body of research shows that AD and especially PD are intricately related to intestinal health and the gut microbiome and that both diseases can spread retrogradely from the gut to the brain. Zeolites are a large family of minerals built by [SiO4]4− and [AlO4]5− tetrahedrons joined by shared oxygen atoms and forming a three-dimensional microporous structure holding water molecules and ions. The most widespread and used zeolite is clinoptilolite, and additionally, mechanically activated clinoptilolites offer further improved beneficial effects. The current review describes and discusses the numerous positive effects of clinoptilolite and its forms on gut health and the gut microbiome, as well as their detoxifying, antioxidative, immunostimulatory, and anti-inflammatory effects, relevant to the treatment of NDs and especially AD and PD. The direct effects of clinoptilolite and its activated forms on AD pathology in vitro and in vivo are also reviewed, as well as the use of zeolites as biosensors and delivery systems related to PD.
