The rosette nanotubes (RNTs) are a class of biologically inspired, self-assembling, metal-free, hydrophilic nanotubes, which hold tremendous potential as targeted drug delivery vehicles. We investigated the cell signaling events caused by lysine-functionalized RNTs (K-RNT) co-assembled with Arg-Gly-Asp-Ser-Lys-functionalized RNTs (RGDSK-RNT) for induction… (More)
An RGDSK (Arg-Gly-Asp-Ser-Lys) modified rosette nanotube (RNT) hydrogel composite with unique surface chemistry and favorable cytocompatibility properties for bone repair was developed and investigated. The RNTs are biologically inspired nanomaterials obtained through the self-assembly of a DNA base analog (G wedge C base) with tailorable chemical… (More)
Today, bone diseases such as bone fractures, osteoporosis and bone cancer represent a common and significant public health problem. The design of biomimetic bone tissue engineering materials that could restore and improve damaged bone tissues provides exciting opportunities to solve the numerous problems associated with traditional orthopedic implants.… (More)
Recently, hydrogels (alginate, agarose, polyethylene glycol, etc.) have been investigated as promising cartilage-healing materials. To further improve cell-material interactions or mechanical properties of such hydrogel scaffolds, many materials (such as ceramics or carbon nanotubes) have been added to produce composites with tailored properties. In this… (More)
When using MLP regression models, some method for estimating the generalisation ability is required to identify badly over and underfitted models. If data is limited, it may be impossible to spare sufficient data for a test set, and leave-one-out crossvalidation may be considered as an alternative method for estimating generalisation ability. However, this… (More)
A one-pot strategy for the nucleation, growth, morphogenesis, and passivation of 1.4 nm Au nanoparticles (NPs) on self-assembled rosette nanotubes (RNTs) is described. Tapping-mode atomic force microscopy, transmission electron microscopy, energy-dispersive X-ray analysis, and selected-area electron diffraction were used to establish the structure and… (More)
A new strategy to access rosette nanotubes with increased inner diameter is presented and demonstrated through the synthesis and self-assembly studies of a tricyclic variant of the Lehn-Mascal G--C base.
OBJECTIVE Limited empirical investigation exists validating the use of Arthur Boothroyd (AB) word recognition materials within the Australian clinical context. The current research was undertaken to examine the evidence base and clinical implementation/interpretation of AB words in Australia. DESIGN An on-line 22-question survey was e-mailed to members of… (More)
A versatile, scaleable, one step synthesis of a lower rim mono-functionalized resorcinarene is described.
