Glucose sensor with enzyme-immobilized membrane by langmuir-blodgett technique.

Membrane topology of cytochrome P450 2B4 in Langmuir-Blodgett monolayers.

Using Langmuir-Blodgett monolayers of both phosphatidylethanolamines and phosphatidylcholines as membrane mimics, we have examined the topology of cytochrome P450 2B4 anchoring. The interaction of wild-type P450 2B4 with phosphatidylethanolamine monolayers can be characterized as a biphasic reaction, with the initial fast phase explained by the specific insertion of membrane-spanning segments o...

Langmuir-Blodgett nanorod assembly.

Techniques for directing the assembly of metal or semiconductor quantum dots into novel superstructures have been extensively pursued over the past decades.1-3 Recent interest has been drawn toward 1-dimensional nanoscale building blocks such as nanotubes, nanowires, and nanorods.4-14 If these one-dimensional nanoscale building blocks can be ordered and rationally assembled into appropriate 2-d...

Enzyme-Mediator Kinetics for Membrane= and Surface- Immobilized Glucose Oxidase

The scanning electrochemical microscope (SECM) can be used to detect electron-transfer reactions of tlp-generated species that occur at nonconductlve surfaces contalnlng a redox-actlve enzyme. Experlments were carrkd out wlth glucose oxldase lmmoblilzed on several substrates and the apparent kinetics of the enzyme catalyds were measured for several medlator oxldants under condltlons of hlgh pgi...

Surface-enhanced Raman scattering by colloidal CdSe nanocrystal submonolayers fabricated by the Langmuir–Blodgett technique

We present the results of an investigation of surface-enhanced Raman scattering (SERS) by optical phonons in colloidal CdSe nanocrystals (NCs) homogeneously deposited on both arrays of Au nanoclusters and Au dimers using the Langmuir-Blodgett technique. The coverage of the deposited NCs was less than one monolayer, as determined by transmission and scanning electron microscopy. SERS by optical ...
