Analysis of protein interactions at native chloroplast membranes by ellipsometry. [PDF]

open access: yesPLoS ONE, 2012
Membrane bound receptors play vital roles in cell signaling, and are the target for many drugs, yet their interactions with ligands are difficult to study by conventional techniques due to the technical difficulty of monitoring these interactions in ...

The effect of polar lipids on tear film dynamics [PDF]

open access: yes, 2009
In this paper we present a mathematical model describing the effect of polar lipids on the evolution of a precorneal tear film, with the aim of explaining the interesting experimentally observed phenomenon that the tear film continues to move upwards ...

Imaging optical thicknesses and separation distances of phospholipid vesicles at solid surfaces [PDF]

open access: yes, 1992
We present the application of reflection interference contrast microscopy (RICM) (1) to map the optical density of supported bilayers and vesicles and (2) to image the contact profile of phospholipid vesicles at surfaces.

How Well Can You Tailor the Charge of Lipid Vesicles? [PDF]

open access: yes, 2019
Knowledge and control of surface charge or potential is important for tailoring colloidal interactions. In this work, we compare widely used zeta potential (ζ) measurements of charged lipid vesicle surface potential to direct measurements using the ...

Atomic force microscopy and Langmuir–Blodgett monolayer technique to assess contact lens deposits and human meibum extracts

open access: yesJournal of Optometry, 2015
Purpose: The purpose of this exploratory study was to investigate the differences in meibomian gland secretions, contact lens (CL) lipid extracts, and CL surface topography between participants with and without meibomian gland dysfunction (MGD). Methods:

Structure and permeability of ion-channels by integrated AFM and waveguide TIRF microscopy. [PDF]

open access: yes, 2014
Membrane ion channels regulate key cellular functions and their activity is dependent on their 3D structure. Atomic force microscopy (AFM) images 3D structure of membrane channels placed on a solid substrate.

From supported membranes to tethered vesicles: lipid bilayers destabilisation at the main transition [PDF]

open access: yes, 2006
We report results concerning the destabilisation of supported phospholipid bilayers in a well-defined geometry. When heating up supported phospholipid membranes deposited on highly hydrophilic glass slides from room temperature (i.e.
