Quantum correlation among photons from a single quantum dot at room temperature
Maxwell's equations successfully describe the statistical properties of fluorescence from an ensemble of atoms or semiconductors in one or more dimensions. But quantization of the radiation field isExpand

Amyloid β-Protein Assembly and Alzheimer's Disease: Dodecamers of Aβ42, but Not of Aβ40, Seed Fibril Formation.
Evidence suggests that oligomers of the 42-residue form of the amyloid β-protein (Aβ), Aβ42, play a critical role in the etiology of Alzheimer's disease (AD). Here we use high resolution atomic forceExpand

External quantum efficiency of single porous silicon nanoparticles
We use a combination of single nanoparticle luminescence and scanning force microscopy to determine the quantum efficiency (QE) of single porous Si nanoparticles and to determine the ratio ofExpand

Photo-activated luminescence of CdSe quantum dot monolayers
We show that the luminescence from CdSe quantum dot monolayers can be strongly influenced by the interaction of water molecules adsorbed on the surface. Light-induced alterations in the surfaceExpand

Intact size-selected Au(n) clusters on a TiO2(110)-(1 x 1) surface at room temperature.
Experiments in which mass-selected gold clusters were deposited on a surface have found that the catalytic properties depend strongly on cluster size. However, these experiments have not establishedExpand

Interactions between Amyloid-β and Tau Fragments Promote Aberrant Aggregates: Implications for Amyloid Toxicity
We have investigated at the oligomeric level interactions between Aβ(25–35) and Tau(273–284), two important fragments of the amyloid-β and Tau proteins, implicated in Alzheimer’s disease. We are ableExpand

Effects of pH and charge state on peptide assembly: the YVIFL model system.
Peptide oligomerization is necessary but not sufficient for amyloid fibril formation. Here, we use a combination of experiments and simulations to understand how pH influences the aggregationExpand
