Janus nanoparticles designed for extended cell surface attachment

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.

Janus 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...

Controlled 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...

Graphitic Surface Attachment by Single-Stranded DNA and Metal Nanoparticles

Graphene and carbon nanotubes are extreme mechanical and electronic materials which have been the subjects of intense study and development since their discoveries. While many of their intrinsic properties have been discovered, their interactions with other materials are only beginning to be explored. The noncovalent binding of single-stranded DNA oligonucleotides to carbon nanotubes and graphe...
