Surface-Tension-Gradient-Induced Pattern Formation in Monolayers

Surface-tension-gradient-induced pattern formation in monolayers.

Pattern formation in gradient systems

Stable and metastable patterned solutions of nonlinear evolution equations of gradient type are discussed. Examples include classes of higher order parabolic PDE's and integrodiierential equations. A governing theme is that patterns can arise as a result of a competition between opposing innuences such as destabilizing and stabilizing mechanisms. The discussion is within the context of a genera...

Chemically induced hairpin formation in DNA monolayers.

A naphthyridine dimer that binds specifically to G-G mismatches has been used to induce hairpin formation in oligonucleotides immobilized onto chemically modified gold surfaces. Surface plasmon resonance (SPR) imaging measurements of DNA microarrays were used to demonstrate that binding of the naphthyridine dimer to G-G mismatches within the stem portion of an immobilized 42-mer oligonucleotide...

Nonequilibrium pattern formation in chiral Langmuir monolayers with transmembrane flows

Studies of pattern formation in nonequilibrium soft matter are essential for understanding the operation of biological cells and for potential applications [1]. Biological membranes including active molecular pumps or channels can develop shape oscillations and show persistent wave propagation [2, 3]. If a membrane contains rotating molecular motors, interactions between them may lead to the de...

Pattern formation and morphology evolution in Langmuir monolayers.

We present a study of how patterns formed by Langmuir monolayer domains of a stable phase, usually solid or liquid condensed, propagate into a metastable one, usually liquid expanded. During this propagation, the interface between the two phases moves as the metastable phase is transformed into the more stable one. The interface becomes unstable and forms patterns as a result of the competition...
