微型和納米字母提供在線快速出版的短篇研究論文，其中包含了微觀和納米科學、工程和技術的最新進展，至少有一個維度從微米到納米不等。微型和納米字母為讀者提供來自微型和納米社區(qū)以及材料和設備社區(qū)的高質量原始研究。在材料科學和微型和納米設備之間彌合這一鴻溝，微型和納米信件解決了工程、物理、化學和生物科學學科的問題。它特別強調跨學科活動和應用。典型主題包括：裝置群落的微觀和納米結構MEMS與NEMS微型和納米級結構、裝置和系統(tǒng)的建模、仿真和實現，并與實驗數據進行比較。合成與加工微和納米光子學分子機器、電路和自組裝有機和無機微觀和納米結構微流體和納米流體

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
