The artificial bilayer structures of lipids and phospholipids can be fabricated using the Langmuir-Blodgett (LB) technique. High sensitivity and ultrasensitive detection can only be achieved using plasmon-enhanced spectroscopy, ...

Surface-enhanced fluorescence (SEF) is rapidly becoming one of the main spectroscopic techniques for the detection of a variety of biomolecules and biomarkers. The main reasons for this trend are the high sensitivity and ...

Coated silver (Ag) colloids synthesized with D-glucose permit the observation of surface-enhanced fluorescence (SEF) and surface-enhanced resonance Raman scattering (SERRS) of the rhodamine B (RhB) molecule. The organic ...

The current paradigm in the field of gene regulation postulates that regulatory information for generating gene expression is organized into modules (enhancers), each containing the information for driving gene expression ...

Contrast enhancement enables the verification of several pathological conditions that lead to vascular changes and/or breakdown of the blood-brain barrier. Examples of diseases that cause these disorders are: neoplastic ...

Three central experimental variables are looked at to increase the observed enhancement factor in plasmon-enhanced fluorescence: nanoparticle size, nanoparticle aggregation, and the sample temperature. The rise in emission ...

Developmental genes can have complex cis-regulatory regions with multiple enhancers. Early work revealed remarkable modularity of enhancers, whereby distinct DNA regions drive gene expression in defined spatiotemporal ...

Gene expression is regulated by promoters, which initiate transcription, and enhancers, which control their temporal and spatial activity. However, the discovery that mammalian enhancers also initiate transcription questions ...

Metal-organic semiconductor films are fabricated as co-evaporated films. It is demonstrated that the technique can be used to fabricate metal-semiconductor surface-enhanced Raman scattering (SERS) or surface-enhanced ...
