We describe for the first time the combination between cross-pair correlation function analysis (pair correlation analysis or pCF) and stimulated emission depletion (STED) to obtain diffusion maps at spatial resolution below the optical diffraction limit (super-resolution). Our approach was tested in systems characterized by high and low signal to noise ratio, i.e. Capsid Like Particles …

Until recently, the diffraction of light had placed a fundamental limit on how far biologists could peer into cells with optical microscopes, preventing them from resolving features less than 250 nm in size, missing critical structures within cells. Over the past 20 years scientists have developed several ingenious techniques allowing them to resolve features as small as …

Cost-effective production of lignocellulosic biofuel requires efficient breakdown of cell walls present in plant biomass to retrieve the wall polysaccharides for fermentation. In-depth knowledge of plant cell wall composition is therefore essential for improving the fuel production process. The precise spatial three-dimensional (3D) organization of cellulose, hemicellulose, pectin and lignin within plant cell walls remains …

PARS complements optogenetics, in that it can reveal circuit-wide effects of optogenetic manipulations and also aid in mapping novel circuits that need tuning in disease. In optogenetics we modify neurons in the rodent brain so that they respond to light and induce a certain behavior in the model organism. When you shine a light, the …
