The nanospheres are transparent but bend and scatter the light that passes through them in predictable ways according to the angle that the light takes when it hits the nanosphere.
The researchers control the nanolithography by altering the size of the nanosphere the duration of light exposures and the angle wavelength and polarization of light.
The researchers can also use one beam of light or multiple beams of light allowing them to create a wide variety of nanostructure designs.
We are using the nanosphere to shape the pattern of light which gives us the ability to shape the resulting nanostructure in three dimensions without using the expensive equipment required by conventional techniques Chang says.
The researchers have shown also that they can get the nanospheres to self-assemble in a regularly-spaced array
We're exploring the use of nanosphere materials other than polystyrene as well as nanoparticle shapes other than spheres Chang says.
Careful optimization of this procedure yielded regular arrays of silver nanospheres on top of the silicon surface,
Next, the nanosphereilicon complex was immersed into a solution of hydrogen peroxide and hydrofluoric acid mixture that eats away at silicon atoms directly underneath the catalytic silver nanospheres.
The pressure, delivered by two diamond plates tightened by four screws to any controlled setting, shepherds silver nanospheres into any desired volume.
#Nanospheres cooled with light to explore the limits of quantum physics A team of scientists at UCL led by Peter Barker
"Nanospheres were cooled with light to explore the limits of quantum physics. Image: James Millen et al.
"The team are still a few degrees short of the temperature required to create quantum behaviour in the glass nanospheres,
And once sufficiently cooled, the team believes the nanospheres should behave according to quantum principles. Once successfully implemented, the technology could allow for highly accurate motion sensors that could detect the slightest tremor,
The paper,"Tunable luminescent carbon nanospheres with well-defined nanoscale chemistry for synchronized imaging and therapy,"is available online:
