Magnetic-mesoporous Janus nanoparticles.
Novel multifunctional magnetic-mesoporous Janus particles with controlled aspect ratio were developed by a simple one-step synthesis approach. Due to their superior magnetic properties and well-defined pore structures, these particles will be important in drug delivery, molecule targeting, cellular imaging, and as building blocks for the assembly of complex nanostructures.
متن کاملJanus Nanoparticles by Interfacial Engineering
The intense research interest in nanoscience and nanotechnology is largely fueled by the unique properties of nanoscale materials that may deviate vastly from those of their constituent atoms and bulk forms. In order to exploit these unprecedented materials properties for the fabrication of next-generation devices and circuitries, two key aspects that are intimately related to each other have t...
متن کاملControlled assembly of Janus nanoparticles.
Janus nanoparticles were prepared by interfacial ligand exchange reactions of octanethiolate-protected gold (AuC8) nanoparticles with 3-mercapto-1,2-propanediol (MPD) at the air/water interface. AFM and TEM measurements showed that the resulting particles formed stable aggregates in water with dimensions up to a few hundred nanometers, in sharp contrast to the original AuC8 particles and bulk-e...
متن کاملThe Janus Character of Heterogeneous Dendritic Nanoparticles
We present a computational and theoretical study of dendrimer-based nanoparticles composed of two linear chain types attached to the terminal groups of a core dendrimer. The chains were coupled to the dendritic core in both topologically Janus and alternating configurations. We find that a straightforward extension of the well-known scaling theory for the size of star polymers due toDaoud andCo...
متن کاملJanus nanoparticles: preparation, characterization, and applications.
In chemical functionalization of colloidal particles, the functional moieties are generally distributed rather homogeneously on the particle surface. Recently, a variety of synthetic protocols have been developed in which particle functionalization may be carried out in a spatially controlled fashion, leading to the production of structurally asymmetrical particles. Janus particles represent th...
