Abstract:

We present a method describing the lateral movement of proteins in cell membranes as observed in FRAP experiments. We extend earlier results derived for normal diffusion [1] to account for the case of anomalous subdiffusion. Our analytic closed forms are compared to computer simulations of anomalous diffusion and both show excellent agreement. The approach sheds light on the behavior of proteins in such complex systems and provides a tool to analyze experimental results.

Abstract:

Single cycle THz emission from unbiased semiconductor devices after ultrafast carrier excitation can be attributed to surge currents on the surface of the device. These currents are due to either drift currents where carriers are accelerated by an internal electric field perpendicular to the surface (surface field effect) or diffusion currents where a separation of charge forms due to electrons and holes having different mobilities (photo-Dember effect). This surface emission is difficult to out couple from the semiconductor device as the emission is parallel to the surface of the semiconducto

Abstract:

As laser devices are scaled down in size and involve the use of photonic structures etched through the active layer - a trend driven by the desire to improve device performance and functionality for future applications in optoelectronic integrated circuits - performance limiting mechanisms such as an increasing internal optical loss, deteriorating gain-mode overlap, lateral carrier out-diffusion and surface recombination can inflict restrictions on the further miniaturisation and overall performance. In this project I have separately evaluated the relative impact of these mechanisms using ridg

Abstract:

The lymphatic endothelial receptor LYVE-1 investigated here is a weak binder to its ligand hyaluronan (HA) and uses receptor clustering to achieve the avidity required for stable interaction to HA. These clustering based interactions are highly dynamic and are often controlled by several molecular players that contribute to receptor functional changes. One such contributor is the cortical actin cytoskeleton. As the actin cytoskeleton lies immediately below the membrane surface, it creates compartments on the membrane that control the receptor organisation, dynamics and allows physical interact

The pulsed field gradient fourier transform nuclear magnetic resonance (PFG-FTNMR) method to measure translational diffusion coefficients in multicomponent systems has been applied to amphiphilic molecules forming liquid crystalline phases. By analyzing the concentration dependence of the diffusion coefficients of water and amphiphile in a micellar system of N,N-dimethyldodecy lamine oxide (DDAO) in water it was possible to conclude that the micelles formed were polydisperse in size and shape. It was also shown that solubilization of small amounts of hydrophobic molecules into the micelles ind

Part One: Role of a pre-formed scaffolding complex in excitatory synapse formation. In order to determine the role of non-synaptic clusters of postsynaptic proteins we monitored the trafficking of several candidate proteins implicated in synaptogenesis, when non-synaptic clusters of scaffold proteins are most abundant. We found a protein complex consisting of two populations that differ in their content, mobility, and involvement in synapse formation. One subpopulation is mobile and relies on actin transport for delivery to nascent and existing synapses. These mobile clusters contain the scaff

Abstract:

Lateral diffusion of membrane components (lipids and proteins) is an important membrane property to measure since the essential process of absorption of anti-cancer and other drugs -some of which are not soluble in lipids and therefore would not be able to penetrate the cell membrane through passive diffusion- lies on it. In particular, the procedure of diffusion into the cell cytoplasm is reliant on free volumes in the membrane (passive diffusion) as well as carrier proteins (facilitated diffusion). By enhancing the mobility of lipids and/or proteins, the possibility of the carrier protein to

From the eye well into extrastriate visual cortex, a preserved spatial representation of the vi- sual world is maintained across many levels of processing.

PNIPAM microgels are “smart” materials that experience a volume phase transition (VPT) at ~32°C, where they undergo a severe loss in volume.

Abstract:

<p>Cells express a variety of proteins on their surface that allows them to sample the world. These proteins are embedded in the plasma membrane, a bilayer of lipids that surrounds the cell. Since the lipid and protein dimensions are in the nanometer range, they are subject to thermal agitation by water molecules and show characteristic diffusive motion. The diffusive movement of these proteins plays a critical role in the cell's ability to react to external signals and regulate its internal environment. </p><p>One prominent application of protein diffusion is in the synaptic connection, where

Abstract:

Lateral diffusion of phospholipids is a process essential to membrane function, and can be measured by nuclear magnetic resonance (NMR). This project will use CODEX (Centerband-Only Detection of Exchange), the most highly-evolved NMR experiment combining magic angle spinning with exchange sensitivity, to measure lateral diffusion. 31P CODEX NMR measurements were performed on phospholipids in small unilamellar vesicles (SUV) in a high viscosity solution to slow the rotational tumbling of the SUV and minimize its influence on the CODEX decay. For SUV composed of 1-palmitoyl-2-oleoyl-sn-glycero-
