We measure the thermal fluctuation of the internal segments of a piece of DNA confined in a nanochannel about 50-100 nm wide. This local thermodynamic property is key to accurate measurement of distances in genomic analysis. For DNA in ~100 nm channe

Membrane protein stoichiometry determined from the step-wise photobleaching of dye-labelled subunits
Many important proteins function as multimeric complexes, which often contain different types and numbers of subunits. Such proteins play a key role in a wide variety of cellular events, including signal transduction, cell regulation, transport and e

Fluorescent carbon nanodots (CNDs) were synthesized in oxidized and reduced forms and were analyzed at the single-particle level. Images of single CNDs at different excitation energies revealed significant heterogeneity in the lower energy trap sites

The solvent dependent study of absorption, fluorescence, and fluorescence excitation spectra of 2-(2'-hydroxyphenyl)-1H-naphth-[2,3-d]-imidazole (HPNI) have indicated the presence of different rotamers and tautomers in the So and S1 states. Similarit

The absorption, fluorescence and fluorescence excitation spectra of 2-(2′-methoxyphenyl)-3H-imidazo[4,5-b]pyridine (2-MPIP) have been studied in five different solvents and at different acid–base concentrations. Semi-empirical quantum mechanical

Spectral characteristics of 2-(2-hydroxyphenyl)benzimidazole (HPBI) have been studied in solutions containing different compositions of dioxane–water mixtures, aqueous sodium dodecyl sulfate (SDS), hexadecyltrimethylammonium bromide (HTAB), and Tri

We describe genome mapping on nanochannel arrays. In this approach, specific sequence motifs in single DNA molecules are fluorescently labeled, and the DNA molecules are uniformly stretched in thousands of silicon channels on a nanofluidic device. Fl

An array of nano-channels was fabricated from silicon based semiconductor materials to stretch long, native dsDNA. Here we present a labeling scheme in which it is possible to identify the location of specific sequences along the stretched DNA molecu
Experimental determination of the free energy (DeltaG) stabilizing the structure of membrane proteins (MPs) in their native environment has been hampered by the aggregation and precipitation of MPs outside the lipid bilayer. We recently demonstrated
