DEK protein, a key chromatin regulator, is strongly overexpressed in various forms of cancer. While conventional microscopy revealed DEK as uniformly distributed within the cell nucleus, advanced super-resolution techniques uncovered cluster-like structures. However, a comprehensive understanding of DEK's cellular distribution and its...

Over the last decades, fluorescence microscopy techniques have been developed in order to provide a deeper, faster and higher resolution imaging of three-dimensional biological samples. Within this framework, Light Sheet Fluorescence Microscopy (LSFM) became an increasingly useful and popular imaging technique able to answer several biological...

The post-synaptic area of the inhibitory synapse is characterized by sub-resolved clusters of the scaffold protein Gephyrin [1] that anchors GABAA receptor (GABAAR). Super-resolution techniques [2] based on Individual Molecule Localization (IML) [3] provide the capability to quantitatively study these subcellular structures, giving access to...

Single Layer Graphene (SLG) has emerged as a critically important nanomaterial due to its unique optical and electrical properties and has become a potential candidate for biomedical applications, biosensors, and tissue engineering. Due to its intrinsic 2D nature, SLG is an ideal surface for the development of large-area biosensors and, due to...

DNA replication stress is a major source of genomic instability and is closely linked to tumor formation and progression. Poly(ADP-ribose)polymerases1/2 (PARP1/2) enzymes are activated in response to replication stress resulting in poly(ADP-ribose) (PAR) synthesis. PARylation plays an important role in the remodelling and repair of impaired...

In this two-part chapter, the background to confocal microscopy and two-photon fluorescence microscopy is first presented, with a detailed description of the optical setup. This is followed by a critical account of the many super-resolution techniques: coordinated stochastic fluorescence microscopy (photoactivation localization microscopy (PALM...
