Antibacterial activity of materials synthesized from clay minerals
نویسندگان
چکیده
The antibacterial activity of silver and cationic surfactant modified smectites from North Patagonian, Argentina, were tested in growth inhibition of Escherichia coli bacteria by the test of susceptibility on solid medium. The exchange reactions were carried out using Ag and hexadecyltrimethylammonium (HDTMA) cations in larger amounts than those conventionally required to form monolayer on the montmorillonite surface. The antimicrobial activity by the tetracyclines continued after the adsorption on the montmorillonite surface. In contrast, the untreated montmorillonite did not show any antibacterial activity against E. coli. The excellent activity shown by the Ag, HDTMA, tetracycline (TC) and minocycline (MC) adsorption complexes provides a promising field of clay mineral application in pharmaceutical applications.

A novel organoclay with antibacterial activity prepared from montmorillonite and Chlorhexidini Acetas.
A series of novel organoclays with antibacterial activity were synthesized using Ca-montmorillonite and Chlorhexidini Acetas (CA) by ion-exchange. The resultant organoclays were characterized using X-ray diffraction (XRD), high-resolution thermogravimetric analysis (HRTG) and Fourier transform infrared spectroscopy (FTIR). Their antibacterial activity was assayed by so-called halo method. In th...
متن کاملKiller Clays! Natural antibacterial clay minerals
Clay minerals have been used in medicinal applications since Aboriginal times (Carretaro, 2002; Wilson, 2003). Clay poultices are used to heal wounds; people eat clays to coat stomach linings and soothe indigestion; animals eat clay containing trace elements (e.g., As) that can kill worms. The reasons that various clay minerals are effective as medicines may be as variable as the ailment, but b...

متن کاملEmission spectroscopy of clay minerals and evidence for poorly crystalline aluminosilicates on Mars from Thermal Emission Spectrometer data
[1] To understand the aqueous history of Mars, it is critical to constrain the alteration mineralogy of the Martian surface. Previously published analyses of thermal infrared (l = 6–25 mm) remote sensing data of Mars suggest that dark regions have 15–20% clay minerals. However, near-infrared (l = 1–3 mm) spectral results generally do not identify widespread clay minerals. Thermal infrared detec...
