Biological Application of Layered Double Hydroxides in Drug Delivery Systems
This review focuses on the extensive study of different layered double hydroxides (LDHs)nanostructures and also their biological and physicochemical (in vitro) properties to encapsulateand deliver drugs with a recognized pharmacokinetic profile in a sustained/modified manner forbetter remedial efficacy contrasted to the corresponding conventional treatments using different<br ...
متن کاملANION EXCHANGE REACTIONS OF LAYERED DOUBLE HYDROXIDES (LDHs) AND LAYERED HYDROXY SALTS (LHSs): QUANTIFICATION OF ION EXCHANGE Abstract Anion exchange reactions of a number of layered double hydroxides with inorganic anions
Anion exchange reactions of a number of layered double hydroxides with inorganic anions were investigated. The five LDH systems used in this study were Mg-Al, Ni-Al, Co-Al, Zn-Al and Zn-Cr. Ni-Zn hydroxynitrate and Ni-Zn hydroxyacetate were the LHSs used in this work. In general, all the LDHs and nickel zinc hydroxysalts exhibited higher extent of exchange towards chloride ions. The extent of e...

متن کاملNomenclature of the hydrotalcite supergroup: natural layered double hydroxides
Layered double hydroxide (LDH) compounds are characterized by structures in which layers with a brucite-like structure carry a net positive charge, usually due to the partial substitution of trivalent octahedrally coordinated cations for divalent cations, giving a general layer formula [(M 1 xM 3+ x)(OH)2] . This positive charge is balanced by anions which are intercalated between the layers. I...
متن کاملAb initio Investigation of Layered Double Hydroxides with Intercalated Herbicides
Layered double hydroxides (LDHs) or hydrotalcite-like compounds exist either as naturally occurring minerals or as synthesized materials by low-cost synthesis methods. LDHs consist of positively charged metal hydroxide layers having the composition [M1–x Mx(OH)2][Ax/m ·nH2O] where M and M are divalent and trivalent cations, respectively. The value of x is the molar fraction and can vary between...
