“…The UV-absorption spectrum was found to be broader compared to the free benzophenone-9, and the nanocomposite was also determined to be biocompatible with HDF cells. 102 Wang et al designed novel UV-absorbing thin film by doping Fe 3+ with Mg/Al LDHs, and the resulting material covered the whole UV region (200-400 nm). Furthermore, the thin film was easily fabricated with highly transparent polymer polysiloxanes and UV-blocking composite material.…”

Hydrotalcite-like compounds are two-dimensional inorganic nanolayers also known as clay minerals or anionic clays or layered double hydroxides/layered hydroxy salts, and have emerged as a single type of material with numerous biomedical applications, such as drug delivery, gene delivery, cosmetics, and biosensing. Inorganic nanolayers are promising materials due to their fascinating properties, such as ease of preparation, ability to intercalate different type of anions (inorganic, organic, biomolecules, and even genes), high thermal stability, delivery of intercalated anions in a sustained manner, high biocompatibility, and easy biodegradation. Inorganic nanolayers have been the focus for researchers over the last decade, resulting in widening application horizons, especially in the field of biomedical science. These nanolayers have been widely applied in drug and gene delivery. They have also been applied in biosensing technology, and most recently in bioimaging science. The suitability of inorganic nanolayers for application in drug delivery, gene delivery, biosensing technology, and bioimaging science makes them ideal materials to be applied for theranostic purposes. In this paper, we review the structure, methods of preparation, and latest advances made by inorganic nanolayers in such biomedical applications as drug delivery, gene delivery, biosensing, and bioimaging.

“…The term "nanomedicine" is a new technology combining the use of both traditional medical technology and nanotechnology where nanosizeengineered materials of less than 100 nm size regime are employed. This interdisciplinary technology covers a wide range of therapeutic applications, from nanoparticulate drug delivery systems (e.g., carbon nanotubes, layered double hydroxides [7][8][9][10][11][12]), to in vitro (e.g., biosensor) and in vivo (e.g., imaging and implantable devices) diagnostics. The intentions of using nanomedicine in drug delivery applications are to achieve (1) improved delivery of water insoluble drugs [13]; (2) delivery of large macromolecule drugs to intracellular sites of action; (3) codelivery of two or more drugs or therapeutic agents for combination treatment; (4) transcytosis of drugs across tight epithelial and endothelial barriers [14]; (5) targeted delivery of drugs in a cell-or tissue-specific manner; (6) real-time read on the in vivo efficacy of a therapeutic agent, and (7) visualization of sites of drug delivery by combining therapeutic agents with imaging probes [15].…”

The revolutionary development of functionalized carbon nanotubes (f-CNTs) for applications in nanomedicine has emerged as one of the most interesting fields, which has increased exponentially in recent years. This is due to their appealing physical and chemical properties, as well as their unique architecture. After a brief introduction on the physicochemical properties of carbon nanotubes (CNTs), we described several functionalization methods for the surface modification of CNTs, with the aim to facilitate their solubility in physiological aqueous environment. This review focuses on recent advances in drug delivery design based onf-CNTs with an emphasis on the determination of various parameters involved and characterization methods used in order to achieve higher therapeutic efficacy of targeted drug delivery. In particular, we will highlight a variety of different analytical techniques which can be used to characterize the elemental composition, chemical structure, and functional groups introduced onto the CNTs after surface modification. We also review the current progress of availablein vitrobiocompatibility assays based onf-CNTs and then discuss their toxicological profile and biodistribution for advanced drug delivery.

Layered double hydroxides have received more attention from researchers due to their range of applications, ease of synthesis and low cost of production. With broader knowledge about solar radiation effects on the body, the use of sunscreens has become even more important. The ability of some nanostructures, such as layered double hydroxides, to act as matrices has made it possible to obtain improvements in photoprotective formulations, with solutions to problems caused by radiation and sunscreens. This review article brings together the most recent advances of these clays, the layered double hydroxides, applied to photoprotection.
