Hierarchical NiCo <sub>2</sub> O <sub>4</sub> @MnMoO <sub>4</sub> core–shell nanomaterial on nickel foam was designed <italic>via</italic> a facile hydrothermal method.
Phenylboronic Acid-Mediated Tumor Targeting of Chitosan Nanoparticles
The phenylboronic acid-conjugated chitosan nanoparticles were prepared by particle surface modification. The size, zeta potential and morphology of the nanoparticles were characterized by dynamic light scattering, zeta potential measurement and transmission electron microscopy. The cellular uptake, tumor penetration,…
Photoresponsive self-healing supramolecular hydrogels for light-induced release of DNA and doxorubicin
An azobenzene-containing cyclic dipeptide PAP-DKP-Lys is a photoresponsive low-MW hydrogelator. The gelation process can be triggered with temperature, pH, light, and ionic strength. The resulting self-healing gels can encapsulate dsDNA or an anticancer drug doxorubicin, and release them in a light-dependent manner.
3-Dimensional porous nanocomposite scaffolds based on cellulose nanofibers for cartilage tissue engineering: tailoring of porosity and mechanical performance
Fully bio-based 3D porous scaffold based on cellulose nanofibers with potential use in cartilage tissue engineering was developed.
Rapid green synthesis of silver and gold nanoparticles using Dendropanax morbifera leaf extract and their anticancer activities.
Dendropanax morbifera Léveille is an oriental medicinal plant that is traditionally used in folk medicine and grows in a specific region of South Korea. We aimed to enhance the utilization of D. morbifera medicinal plants for synthesis of silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs). D. morbifera leaf e…
SnS 2 nanoflakes for efficient humidity and alcohol sensing at room temperature
We report a one step facile hydrothermal synthesis of layered SnS <sub>2</sub> nanoflakes and its application as humidity and alcohol sensor.
Super color purity green quantum dot light-emitting diodes fabricated by using CdSe/CdS nanoplatelets
Colloidal nanoplatelets (NPLs) have recently been introduced as semiconductor emissive materials for the fabrication of quantum dot light-emitting diodes (QLED) on account of their ultra-narrow photoluminescence (PL) linewidth. In this paper, we report a multilayer all solution-processed green QLED based on colloidal…
Zinc ion-doped carbon dots with strong yellow photoluminescence
Carbon dots doped with zinc ions and displaying strong yellow photoluminescence and a QY of 51.2% were produced, as were various applications of these carbon dots.
Tuning the electronic properties of monolayer and bilayer PtSe 2 via strain engineering
Based on the first-principles computations we show that the band gaps of monolayer and bilayer PtSe <sub>2</sub> can be tuned over a wide range <italic>via</italic> strain engineering.
Excitation-independent carbon dots, from photoluminescence mechanism to single-color application
Green- and Blue-Cdots were obtained with excitation-independent emission. The PL mechanism of the Cdots was proposed based on their optical properties and structure. Their single-color application was validated with doubly encrypted characters.
Block copolymer self-assembly–directed synthesis of mesoporous gyroidal superconductors
Superconductors with periodically ordered mesoporous structures are expected to have properties very different from those of their bulk counterparts. Systematic studies of such phenomena to date are sparse, however, because of a lack of versatile synthetic approaches to such materials. We demonstrate the formation of…
