The combination of flow cytometry and X-ray fluorescence enables semi-quantitative estimation of cellular SiO2 nanoparticles and their biological effects.
Micro-/Nanotechnology
Carbon nanotube broadband polarisers
Cole et al. report the fabrication of free-standing, horizontally aligned carbon nanotube membranes.
Are single-walled carbon nanotubes derived from a zigzag graphene ribbon?
Researchers report that SWCNTs are tubular graphene in a unique armchair configuration, resulting from the growth of a zigzag graphene ribbon.
Hybrid graphene–giant nanocrystal quantum dot assemblies
New work shows that new class of nanocrystals coupled to graphene causes bi-excitons to experience recombination and simultaneous emission of photon pairs.
Exploring the possibilities and limitations of a nanomaterials genome
Professor Geoff Ozin and co-workers aim to categorise and organise the multifaceted properties and behaviours of nanomaterials.
Stimuli-responsive dynamic hydrogels
A team have developed the first stimuli-responsive protein hydrogel whose mechanical properties can be dynamically tuned in response to external stimuli.
Inkjet printing and metal nanoparticles combine to shrink electronics
new research has combined inkjet printing and metal nanoparticle inks as a novel, low-cost solution for interconnect fabrication.
Gold nanorods shown to inhibit migratory of metastatic cancer
Research shows that gold nanorods effectively inhibit the migratory and invasive properties of various metastatic cancer cell lines in vitro and in vivo.
Non-fouling nanoparticulate surfaces
A Harvard research team has used a layer-by-layer technique to assemble a nanostructured surface coating infused with a fluorocarbon-based lubricant.
DIY Surface-enhanced Raman spectroscopy sensor
A team have combined “lab-on-paper” technology with SERS to provide a label-free, ultrasensitive and powerful tool for the detection of specific molecules.
