The internet database report tells that number of articles related to nanofibers exceeds 8,000 in Japan as of 2015.

As shown in Fig. 7, number of contribu-tions have been rapidly increasing since2006.
More than 1,000 articles are being contributed and researches are actively being made all over Japan.

2) Research trends

Commercial products that contain nanofibers such as high performance filters and face masks have already been available in the market.
They made use of nanofibers of high dust collection efficiency and low pressure loss.

In the field of regenarative medicine materials that utilize high adhesion to cells and porosity of nanofibers are developed for scaffolds.

Research for composite materials of nanofibers and particles are being conducted worldwide.  Materials for the following applications are also under development by making use of features of the both.

・ Electrodes
・ Separation membranes
・ Conductive membranes
・ Sensors
・ Wound treatment
・ Drug delivery system
・ Functional food
・ Functional clothes
・ Functional paint
