At present, sensor has been broadly used in space industry, ship industry, civil structures, electric industry, oil and chemical industry, and medicine fields. Nanotechnology provides a novel platform for the manipulation of sensitive material in atomic and molecular scales.

In the recent literature, many significant contributions to both nanofiber sensing and gas sensing nanomaterials have been made. Fiber diameter in nanoscale effectively reduces the transmission loss, bending loss, and coupling loss of the sensitive material, which will be conducive to raising the level of application in safety monitoring of civil engineering, helicopter rotor, nuclear plant, and so on. Meanwhile, gas sensors based on nanomaterials exhibit ultrahigh detectivity, specificity, low-power consumption, multifunctionality, and miniaturized size.

This special issue aims to enhance the fundamental understanding and the sensing applications of nanomaterials. We are specifically interested in paper elaborating the modeling and simulation work that combined with the preparation of nanomaterials and nanosensors. The research on novel sensing principles or functions in nanoscale is also encouraged. Both original research findings and review articles are invited to contribute to this special issue.

Potential topics include, but are not limited to:

• Nanomaterials with novel morphology
