What are Langmuir Monolayers?

A Langmuir monolayer (LM) is a monomolecular amphiphilic film at the air-water interface. Each amphiphilic molecule consists of a polar head group (hydrophilic moiety) and a nonpolar tail typically a hydrocarbon (hydrophobic) chain. Typical examples are fatty acids, lipids, alcohols and others.

Introduction and Motivation

Introduction and Motivation
Our goal is to develop techniques to create artificial macromoluclar membranes and determine their structure and physical properties on the molecular length scale. Our studies are multi-disciplinary encompassing the following areas:

Surface Chemistry
By mimicking biomineralization and recognition processes, adsorption and crystallization of unique monomolecular membranes can be formed from solutions.

Cascading Style Sheets

Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can also be applied to any kind of XML document, including SVG and XUL.
