Design of patchy particles using ternary self - assembled monolayers In
Recent simulations have studied the formation of patterns in a binary mixture of immiscible surfactants adsorbed onto the surface of a spherical nanoparticle. The resulting patterns (Janus, spots and stripes) were in good agreement with experimental results. We perform dissipative particle dynamics (DPD) simulations to study the patterns obtained by adding a third surfactant to the monolayer as...
متن کاملDesign of patchy particles using quaternary self-assembled monolayers.
Binary and ternary self-assembled monolayers (SAMs) adsorbed on gold nanoparticles (NPs) have been previously studied for their propensity to form novel and unexpected patterns. The patterns found were shown to arise from a competition between immiscibilty of unlike surfactants and entropic gains due to length or other architectural differences between them. We investigate patterns self-assembl...
متن کاملSelf-Assembly of Patchy Particles.
Molecular simulations are performed to study the self-assembly of particles with discrete, attractive interaction sites - "patches" - at prescribed locations on the particle surface. Chains, sheets, rings, icosahedra, square pyramids, tetrahedra, and twisted and staircase structures are obtained through suitable design of the surface pattern of patches. Our simulations predict that the spontane...
متن کاملCrystallization on Self Assembled Monolayers
Over the past two decades, self assembled monolayers (SAMs) (Love et al., 2005; Smith et al., 2004; Ulman, 1996) have been extensively studied due to their many applications in various fields such as electrochemistry (Eckerman et al., 2010), biosensors (Nyquist et al., 2000), protein separation (Chun and Stroeve, 2002) and enantiomer separation (Mastai, 2009). SAMs are organic assemblies formed...
متن کاملSelf Assembled Monolayers -A Review
Self assembly provides a simple route to organise suitable organic molecules on noble metal surface by using long chain organic molecules with various functionalities like -SH,-COOH,-NH2 , Silanes etc. These surfaces can be used to build up interesting nano level architectures. Self assembly is an interesting process for biological relevance because it provides a novel approach to complex struc...
