Illustration of confining light to nano-gaps with gold plasmon nanostructures

Creating and manipulating condensed matter through self- and directed-assembly on the nanoscale to create nano-systems with unusual properties opens up many new areas of science which are highly interdisciplinary.

 

DNA origami nanomachine assembling metal nanoparticles

These explore how atoms, molecules, inorganic components such as semiconductor/ metallic complex nanoparticles, and (bio)polymers, can be combined into nanostructures that have new functional properties when they confine and modify the behaviour of light, emitters, magnetism, charge and particle flow, dipoles, forces, spin, thermal, and other properties.

Improved function opens up high-impact basic science but also underpins the technologies of the future, holding the key to low-energy information technologies, healthcare sensing, sustainable materials, security, and the internet of things. This therefore combines discovery science with many application perspectives.

The theme is strongly interdisciplinary involving many collaborative research programmes with other Departments in the Schools of Physical Sciences, Technology and the Biological Sciences.

Some examples of the huge diversity of research and applications are given below.
