Nanotechnology and nanomaterials: Promises for improved tissue regeneration
Publication year: 2008
Source: Nano Today, In Press, Corrected Proof, Available online 7 November 2008
Lijie, Zhang , Thomas J., Webster
Tissue engineering and regenerative medicine aim to develop biological substitutes that restore, maintain, or improve damaged tissue and organ functionality. While tissue engineering and regenerative medicine have hinted at much promise in the last several decades, significant research is still required to provide exciting alternative materials to finally solve the numerous problems associated with traditional implants. Nanotechnology, or the use of nanomaterials (defined as those materials with constituent dimensions less than 100nm), may have the answers since only these materials can mimic surface properties (including topography, energy, etc.) of natural tissues. For these reasons, over the last decade, nanomaterials have...

Zhenmeng, Peng , Hong, Yang
Recent advances in the design and preparation of platinum-based nanostructures and their applications as electrocatalysts for low-temperature fuel cells are reviewed. Discussions are focused on the fundamental understanding and new experimental designs in the control of shape, composition and nanoscale structure of platinum and its alloy particles in colloidal systems. We explain the formation of various heteronanostructures using the Frank–van der Merwe (FM), Volmer–Weber (VW) and Stranski–Krastanov (SK) growth modes. Phenomena that exist in nanometer-sized regime, such as the disappearance of miscibility gaps for certain platinum alloys are given special attentions. The relationship between electronic structure or surface atomic arrangement...

Several biocompatible polymers are capable of large responses to small temperature changes around 37°C. In water, their responses include shrinkage and swelling as well as transitions in wettability. These properties have been harnessed for biomedical applications such as tissue engineering scaffolds and drug delivery carriers. A soft material/hard material hybrid in which a magnetic metal or oxide is embedded in a temperature-responsive polymer matrix can combine the thermal sensitivity with magnetic signatures. Importantly, nanosizing such construct brings about new desirable features of extremely fast thermal response time, small magnetic hysteresis and enhanced magnetic susceptibility. Remote magnetic maneuvering and heating of...

Platinum has been widely used in many applications, especially for catalysis and fuel cell technology due to its ability to maneuver both oxidation and reduction reactions. In addition to size, the shape or morphology of a Pt nanocrystal provides a sensitive knob for tuning its catalytic and electrocatalytic properties. A number of chemical routes have been developed to produce Pt nanocrystals with well-defined and controllable shapes to improve their performance in terms of catalytic activity and selectivity. Conventional polyhedrons (e.g., cubes, octahedrons, and tetrahedrons) and their overgrown structures (e.g., multipods) have all been obtained in reasonably high yields, as well...

Ferromagnetism as a universal feature of inorganic nanoparticles
Publication year: 2008
Source: Nano Today, In Press, Corrected Proof, Available online 31 October 2008
A., Sundaresan , C.N.R., Rao
Room-temperature ferromagnetism is exhibited by nanoparticles of a variety of inorganic materials although they are intrinsically non-magnetic. Typical of such nanomaterials are the oxides, CeO2, TiO2, Al2O3, and MgO. Nanoparticles of nitrides such as GaN and chalcogenides such as CdS and CdSe also exhibit ferromagnetism. Ferromagnetism of the nanoparticles is confined to the surface. This phenomenon has been utilized to render the classic ferroelectric BaTiO3 to be multiferroic wherein surface ferromagnetism coexists with bulk ferroelectricity. Interestingly, nanoparticles of superconducting YBa2Cu3O7 show surface ferromagnetism. It is possible that surface ferromagnetism of inorganic nanoparticles can be usefully exploited.

This study demonstrated the design and synthesis of chiral or achiral poly-imidazolium/poly-imidazolidium spherical particles. Particles with diameters in the range of nanometers to micrometers were formed spontaneously with certain spacer groups. The novel polymer particles have a rigid main-chain network structure. The parent ionic polymer particles could be easily transformed to stable poly-N-heterocyclic carbene (poly-NHC) particles and poly-NHC-metal organometallic particles with tailored chemical and physical properties. These colloidal nanoparticles and microparticles provided a unique platform for manipulating the versatile carbene chemistry. Poly-NHC-Pd particles exhibited excellent activity and recyclability in heterogeneous Suzuki cross-coupling reactions.

Self-assembling peptide nanotubes
Publication year: 2008
Source: Nano Today, Volume 3, Issues 3-4, June-August 2008, Pages 22-30
Shane, Scanlon , Amalia, Aggeli
Biological proteins and peptides have the intrinsic ability to self-assemble into elongated solid nanofibrils[1], [2], [3], [4], [5], [6] and [7], which may give rise to amyloid diseases[8], [9], [10] and [11] or inspire applications ranging from tissue engineering to nanoelectronics[12], [13], [14], [15] and [16]. Proteinaceous fibrils are extensively studied and well understood, to the extent that detailed theoretical models have been proposed that explain and predict their behavior[17] and [18]. Another intriguing state of protein-like self-assembly is that of nanotubes (NTs), defined here as an elongated nano-object with a definite inner hole. In contrast to proteinaceous fibrils, nanotubes...

Novel nanostructures for SERS biosensing
Publication year: 2008
Source: Nano Today, Volume 3, Issues 3-4, June-August 2008, Pages 31-37
Ralph A., Tripp , Richard A., Dluhy , Yiping, Zhao
Surface-enhanced Raman scattering (SERS) is a powerful analytical tool for chemical and biological sensing applications. However, one feature which has limited its use in biosensing applications is the difficulty involved in producing uniform, highly sensitive, and reproducible SERS substrates. Recent developments in oblique angle deposition and other nanofabrication techniques have overcome this limitation, providing an unprecedented opportunity to develop SERS substrates for pathogen biosensor applications. Recently reported examples of SERS's newfound sensing abilities include the capacity to detect low levels of viruses and bacteria, as well as to discriminate between types and strains of pathogens, including pathogens with gene deletions....

One of the most important classes of synthetic systems for creating self-assembled nanostructures is amphiphilic block copolymers. By controlling the architecture of individual molecules, it is possible to generate nanostructures either in an undiluted melt or in solution. These ordered nanostructures are tunable over a broad variety of morphologies, ranging from discrete micelles and vesicles to continuous network structures. Their synthetic nature allows the design of interfaces with different chemical functional groups and geometrical properties. This, in combination with molecular architecture, determines the levels of ordering in self-organizing polymeric materials. For these and other reasons, block copolymer micelles, vesicles, and...
