Micro & Nano Letters offers express online publication of short research papers containing the latest advances in micro and nano-scale science, engineering and technology, with at least one dimension ranging from micrometers to nanometers. Micro & Nano Letters offers readers high-quality original research from both the micro and nano communities, and the materials and devices communities.Bridging this gap between materials science and micro and nano-scale devices, Micro & Nano Letters addresses issues in the disciplines of engineering, physical, chemical, and biological science. It places particular emphasis on cross-disciplinary activities and applications.Typical topics include:Micro and nanostructures for the device communitiesMEMS and NEMSModelling, simulation and realisation of micro and nanoscale structures, devices and systems, with comparisons to experimental dataSynthesis and processingMicro and nano-photonicsMolecular machines, circuits and self-assemblyOrganic and inorganic micro and nanostructuresMicro and nano-fluidics
