Abstract / Description of output

The behaviour of colloids has become an ever expanding area of research due to the increasing number of applications in both scientific and industrial fields where their unique properties are being exploited. Such areas include bio sensors, catalyst processes, microelectronics industry and drug delivery applications. In this chapter we introduce the fundamental ideas and concepts behind the reversible self-assembly of colloidal particles on solid surfaces. The emphasis is on ultrathin films, monolayers and sub-monolayers with colloidal particles of diameter of 100 nm or lower. We provide examples of three systems (colloidal silica, magnetite and high-functionality star-shaped polymers) which highlight the importance of various interactions (electrostatic, van der Waals, steric) and small scale effects (immersion capillary forces and dewetting instabilities). Furthermore, we discuss issues associated with size and softness of the nanoparticles and the different underlying physical mechanisms that govern their behaviour.
