A novel fluorescent DNA sensor system based on polydopamine modified MgAl-layered double hydroxides

Direct contact, dissolution and generation of reactive oxygen species: How to optimize the antibacterial effects of layered double hydroxides

“…Among the various inorganic materials, layered double hydroxides (LDHs) were extensively studied due to their interesting properties as anion exchangeability, compositional flexibility, and biocompatibility, thus making them good candidates for several potential applications as catalysis [12,13], sorption of pollutants [14,15], biosensors [16], drug storage delivery [17,18], and antimicrobial materials [12,[19][20][21][22]. Layered double hydroxides (LDHs), also known as anionic clays, are lamellar solids having a general formula expressed as [M(II)(1−x) M(III)x (OH)2] x+ [A n− x/n…”

Nanoclay-based sensor composites for the facile detection of molecular antioxidants

“…34–37 Moreover, LDHs have already demonstrated their potential in the fabrication of various sensors. 38–41 An an anionic polyelectrolyte, sodium alginate (NaAlg) was applied to control the surface charge of dLDH particles, while the antioxidant sensing nature was achieved by functionalization of the polyelectrolyte coated nanosheets with the Cu(Nc) 2 complex. The structure and composition of the obtained sensing composite were explored by microscopy, spectroscopy and light scattering techniques.…”

“…Zn 2+ , Cu 2+ , Ag + [12,46,49,52], by which these released soluble cations could contribute to the antibacterial activity. Finally, the third LDH antibacterial mechanism is the generation of reactive oxygen species (ROS) by pristine and NPsloaded LDHs to yield an efficient antibacterial effect [16,38,[46][47][48]53]. .…”
