A novel methanol derived graphene (MDG) and gentamicin sulfate nanohybrid was prepared, and the loading and release behaviour of gentamicin on MDG is investigated. An efficient drug loading of 2.57 mg mg(-1) was obtained at pH 7. By applying release kinetic models, the mechanism of release of the drug from the MDG matrix was found to be following the Korsmeyer-Peppas model. However, the diffusi...

Assembly of paramagnetic Cu(2) complexes with a Schiff base scaffold possessing extended electron delocalization together with a quasi-planar structure onto carbon nanotubes induces a diameter-selective charge transfer from the complex to the nanotubes leading to an interestingly large and tunable ambipolar effect. We used complementary techniques such as electron paramagnetic resonance, absorp...

In a smart solution-processable luminescent poly(norbornene)/oxazine-1 (Ox1) intercalated fluoromica nanohybrid, the supramolecular organization of the Ox1 dyes can be tuned at the nanoscale level and a deep red emission band switched on by inducing a phase segregation of aligned molecules within the fluoromica layered scaffold. By combining low-temperature photoluminescence and ultrafast pump-...

In recent years, the development and deployment of nano-immobilized lipases, as robust biocatalysts, has appeared a promising alternative for biodiesel production. There is significant hike in using nano-sized support matrices enzyme-based biotransformation bioprocesses with ever-increasing scientific awareness nanotechnological advancement. Several nano-scale materials include magnetic non-mag...

Abstract Background The distribution of drugs could not be controlled in the conventional delivery systems. This has led to developing a specific nanoparticle-based system, called smart drug In cancer therapy, innovative biocompatible nanocarriers have received much attention for various ranges anti-cancer drugs. this work, effect an interesting and novel copolymer named "dimethyl acrylamide-tr...

Bimetallic nitrides are now being considered as one of the emerging advanced functional materials due to their characteristic features and remarkable physicochemical properties. Herein, we report a new crystalline bimetallic nitride (Co3ZnN) that belongs to the cubic crystal phase, which was successfully synthesized through direct nitridation of metallic salts as precursors. Co3ZnN nanoparticle...

Electroconductive hydrogels with stimuli-free self-healing and self-recovery (SELF) properties high mechanical strength for wearable strain sensors is an area of intensive research activity at the moment. Most electroconductive hydrogels, however, consist static bonds dynamic SELF performance, presenting a challenge to improve both into one single hydrogel. An alternative strategy successfully ...

Background and Aim: The use of composite restorations has increased in recent years. One of the most important problems with composite restorations is the loss of consistency between the composite and tooth color, which in most cases requires replacement. Materials and Methods: In this study, the color stability of 40 disc-shaped specimens (10 mm in diameter and 2 mm in height) from two types ...

Malignant glioma is one of the most untreatable cancers because of the formidable blood-brain barrier (BBB), through which few therapeutics can penetrate and reach the tumors. Biologics have been booming in cancer therapy in the past two decades, but their application in brain tumor has long been ignored due to the impermeable nature of BBB against effective delivery of biologics. Indeed, it is...
