We have developed a colorimetric assay for DNA detection based on the aggregation of
unmodified metallic nanoparticles. Charge neutral peptide nucleic acids (PNA) are used as …

An important point regarding the development of stable biofunctional nanoparticles for
biomedical applications is their potential for aspecific interactions with the molecules of the …

A novel synthetic route to peptide-capped gold nanoparticles was demonstrated herein.
Tetrachloroaurate ions were reduced with 2-[4-(2-hydroxyethyl)-1-piperazinyl] …

Quantifying carbohydrate–protein (ligand–receptor) interactions is important to understand
diverse biological processes and to develop new diagnostic and therapeutic methods. We …

Stable SERS response originating from gold nanoparticles (Au NPs) is demonstrated for the
first time to be suitable for detection of heparin with high selectivity. Herein we report a novel …

Chondroitin sulfate (CS) is an important glycosaminoglycan that has been implicated in
several disease processes, such as cancer and spinal cord injury. However, few studies …

An important feature necessary for biological stability of gold nanoparticles is resistance to
ligand exchange. Here, we design and synthesize self-assembled monolayers of mixtures of …

The importance of having nanoparticles that are soluble, stable, and that have no non-
specific binding is often overlooked, but essential for their use in biology. This is particularly …

Abstract The alpha-2, 8-linked form of the polysaccharide polysialic acid (PSA) has
widespread implications in physiological and pathological processes, ranging from …

The number of patents that is increasing in the field of radiopharmacy from 2000 until 2013
are over 4500 patents that have been deposited nationaly and internationally. However …
