Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.

Nano-Micro Letters publishes articles that focus on, but are not limited to, the following areas:
- Synthesis, characterization, manipulation of nanomaterials
- Quantum physics, nanoscale electrical transport
- Nanoscale modeling and simulations
- Microdevices based on nanomaterials or nanostructures
- MEMS, NEMS
- Nanosensors, Nanoelectronics, Nanomagnetics
- Nano- or microfluids
- Nanobiology, biotechnology, bioengineering
- Nanomedicine
- Solar cell based on nanostructures and nanomaterials
- Applications related with nano- and micromaterials, devices and systems

Article types
Research articles 
Reports of original research work that has not been published previously; not normally more than 8500 words (10 journal pages). Papers on nano-and microscale theories, technologies, engineering and applications should include some representative results. Claims for originality or novelty of researches should be clearly stated in the abstracts.

Reviews         
These are intended to summarize accepted practice and report on recent progress in selected areas; not normally more than 15000 words (15 journal pages). Reviews must be high quality, authoritative, state-of-the-art accounts of the selected research field, including historical reviews, recent advances and perspectives for future development. Reviews should not contain unpublished original research. All cited figures/tables should have copyrights.

Communications      
Brief, urgent announcements of significant advances or preliminary accounts of new work, not more than 3500 words (4 journal pages). The most important criteria for acceptance of a Rapid communication are novelty and significance. For these articles authors must state briefly, in a covering letter, exactly why their works merit rapid publication.

Perspectives   
Articles are short readable articles covering current areas of interest, including the latest developments, viewpoints on recent progress. Perspectives are personal reviews of a field or area, and they are focused rather than comprehensive. Perspectives should not exceed 4000 words total. They should have a title, an abstract, a few references, and one or two tables and figures.

Commentaries
Commentaries present a more in-depth analysis or a new insight into a previously published material. They should be of around 1500 - 3000 words total. A title, an abstract, a few references, and one or two tables and figures should be included in a commentary.

Highlights      
Articles are short readable articles that highlight important new developments covering developments made over the past year or so. They should explain the significance of these developments and may also identify where further works will be urgently required or where challenges are still faced.
