Analysis of calorimetric and crystallographic information shows that the α-helix is maintained not only by the hydrogen bonds between its polar peptide groups, as originally supposed, but also by van der Waals interactions between tightly packed apo

The nature of water on the surface of a macromolecule is reflected in the temperature dependence of the heat effect, i.e., the heat capacity change, ΔCp, that accompanies its removal on forming a complex. The relationship between ΔCp and the nature

We previously reported that neuraminidase (NA) pretreatment of human PBMCs markedly increased their cytokine response to lipopolysaccharide (LPS). To study the mechanisms by which this occurs, we transfected HEK293T cells with plasmids encoding TLR4,

The heat capacity change, ΔCp, accompanying the folding/unfolding of macromolecules reflects their changing state of hydration. Thermal denaturation of the DNA duplex is characterized by an increase in ΔCp but of much lower magnitude than observed

We present a potentially highly sensitive and selective bio-assay for the potential detection of any five different DNA sequences from one sample in one well. The assay is based on a DNA "rapid catch and signal" (DNA-RCS) technology developed for the

We present an innovative “Rapid Catch and Signal” (DNA-RCS) technology for the simultaneous highly selective detection of multiple specific DNA sequences in solution. The DNA-RCS technology combines advantages of microwave-accelerated DNA hybridi

A new and perspective addition to traditional fluorescent probes is the Au clusters (8–25 atoms) which can label proteins, rendering them extremely bright and photostable. In this paper, we show that albumins can quickly and effectively be labeled

The fluorescence spectrum of Au-clusters (8- and 25-atom), which covers the spectral range 350–900 nm, is dramatically enhanced in the presence of plasmon supporting plate-well deposited nanoparticles. The wavelength-dependent metal-enhanced fluore

Structural modifications to interacting systems frequently lead to changes in both the enthalpy (heat) and entropy of the process that compensate each other, so that the Gibbs free energy is little changed: a major barrier to the development of lead

In recent years both the mechanism and applications of metal-enhanced fluorescence (MEF) have attracted significant attention, yet many fundamental aspects of MEF remain unanswered or addressed. In this study, we address a fundamental aspect of MEF.
