Nanoscale Editor features in Chemistry World

15 Aug 2012

By Jane Hordern, Deputy Editor.

Nanoscale Associate Editor Professor Xiao Cheng Zeng‘s latest discovery has featured in Chemistry World this week. Zeng and colleagues have calculated the structure of a stable carbon dication with a coordination number of 7, higher than any yet seen experimentally.

Carbon clusters score lucky seven

US and Chinese chemists say that they’ve calculated the structure of a stable carbon dication that would have a higher coordination number than any yet seen experimentally. Xiao Cheng Zeng from the University of Nebraska-Lincoln and colleagues have found that a carbon surrounded with seven titanium atoms can fulfil the necessary stability criteria. ‘We examined all first-row transition-metal elements and most main group elements,’ Zeng tells Chemistry World. ‘Only titanium fits thus far.’

Surrounding carbon with more than four other atoms moves beyond conventional two-centre, two-electron bonds to arrangements sharing fractional numbers of valence electrons. The current record largest cluster seen experimentally was a hexacoordinate carbon structure synthesised by Japanese researchers in 2008. But theoretical physical chemists are curious to see how much further coordination numbers might be pushed.

Nano-injection delivery method for single cells

06 Aug 2012

By Jane Hordern, Deputy Editor.

Voltage controlled delivery of materials for ‘single-cell surgery’

A system that enables controlled delivery of materials into a single cell without the need for highly specialised manual operation has been developed by US scientists.

The system is fully electrical, is based on double-barrel nanopipettes and is capable of injecting a controlled amount of material into a single cell. It uses a scanning ion conductance microscope (SICM) to position a nanopipette within a few hundred nanometres of the cell membrane. The amount of material delivered to the cell is controlled by the amplitude and duration of an applied voltage. The team injected human fibroblasts with carboxyfluorescein as a proof-of-principle experiment.

Traditional micropipettes suffer from several drawbacks, e.g. large size relative to typical cells, low cell viability following injection and requirement of skilled operator. More recently developed atomic force microscopy-based nanoinjectors are limited in terms of throughput and control of injection volumes.

This new system overcomes many of these concerns, including very good cell viability (70-100 %), with normal cell division observed 27 hours post-injection. In addition, the authors were able to inject two different dyes into the cells without any cross-talk observed between the two; this gives rise to the possibility of build in more chambers and customise specific cocktails of molecules for different cells.

Pinning down cancer

18 Jul 2012

By Aliya Anwar.

US scientists have synthesised pin-shaped nanoparticles with magnetic and optical properties. The team, led by Xiaohua Huang at the University of Memphis, says that the nanoparticles ‘could be used for magnetic resonance imaging (MRI), early detection and photothermal therapy of cancer and other diseases’.

Nanoparticles with both magnetic and optical properties are highly sought after in a number of fields, particularly medicine, where they could be efficient agents for imaging tumour cells using surface enhanced Raman scattering (SERS) and MRI.
