Fast and automatic processing of multi-level events in nanopore translocation experiments

Aleksandra Radenovic, Michael Graf, Camille Alice Raillon, Lorenz Jan Steinbock

We have developed a method to analyze in detail, translocation events providing a novel and flexible tool for data analysis of nanopore experiments. Our program, called OpenNanopore, is based on the cumulative sums algorithm (CUSUM algorithm). This algorit ...

Identification of the factors affecting co-localization precision for quantitative multicolor localization microscopy

Aleksandra Radenovic, Paolo Annibale, Marco Scarselli, Mattia Greco

This work explores the potential of multi-color Photoactivated Localization Microscopy (PALM) imaging to probe sub-diffraction limit interactions between proteins with spectrally separated labels. Using a PALM setup built around a commercial microscope axi ...

Micro-fabrication process for small transport devices of layered manganite

Andras Kis, Aleksandra Radenovic, Henrik Moodysson Rønnow, Arash Alahgholipour Omrani

Devices have been fabricated based on the bilayer manganite La1.4Sr1.6Mn2O7, which in the bulk state orders magnetically below 90 K, at which point both in-plane and c-axis bulk resistivity decrease by 2-3 orders of magnitude. We provide an optimized proce ...

ssDNA Binding Reveals the Atomic Structure of Graphene

Andras Kis, Aleksandra Radenovic, Paolo Annibale, Floriano Traversi

We used AFM to investigate the interaction of polyelectrolytes such as ssDNA and dsDNA molecules with graphene as a substrate. Graphene is an appropriate substrate due to its planarity, relatively large surfaces that are detectable via an optical microscop ...

Photoactivatable Fluorescent Protein mEos2 Displays Repeated Photoactivation after a Long-Lived Dark State in the Red Photoconverted Form

Aleksandra Radenovic, Paolo Annibale, Marco Scarselli

Illumination with 405 nm light can recover the emission for single green fluorescent protein (GFP) mutants that have gone into a long-lived dark state. The reported behavior is the standard for the reverse photoswitchable protein Dronpa and its mutants. Ho ...

Fabrication of 10 nm diameter hydrocarbon nanopores

Aleksandra Radenovic

The addition of carbon to samples, during transmission electron microscope imaging, presents a barrier to accurate analysis; the controlled deposition of hydrocarbons by a focused electron beam can be a useful technique for local nanometer-scale sculpting ...
