Dermatophytes are usually isolated from house dust by using actidione-chloramphenicol Sabouraud glucose medium (
ACS
medium). We have prepared a new medium, 5FC medium, by adding gentamicin sulphate (GS) and 5-fluorocytosine (5FC) to
ACS
medium to achieve more efficient isolation of dermatophytes from house dust. 5FC medium was more effective in isolating dermatophytes than
ACS
medium or
ACS
medium supplemented with GS alone. Trichophyton rubrum could be grown from 13 out of 19 house dust samples from the homes of patients with
tinea pedis
(68.4%), and T. mentagrophytes could be grown from 17 out of 21 (81.0%). Two of 20 house dust samples from the home of a control family without dermatophytosis grew only one colony of dermatophytes in 5FC medium; the rest of the samples showed no growth. The number of colonies isolated on 5FC medium was much higher than on
ACS
medium (5.3 vs. 2.0 for T. rubrum and 17.2 vs. 2.1 for T. mentagrophytes). In addition, the size of the isolated colonies was much larger than that on
ACS
medium. Thus, 5FC medium can be regarded as a useful tool for isolating dermatophytes from various contaminated samples.

As a green and eco-friendly technology, triboelectric nanogenerator (TENG) can harvest energy from human motion to generate electricity, so TENGs have been widely applied in wearable electronic devices to replace traditional batteries. However, the surface of these TENGs is easily contaminated and breeds bacteria, which is a threat to human health. Here, we report an antibacterial composite film-based triboelectric nanogenerator (ACF-TENG) that uses Ag-exchanged zeolite (Ag-zeolite) and polypropylene (PP) composite film as the triboelectric layer. Adding a small amount of Ag-zeolite with excellent antibacterial properties can increase the dielectric permittivity and improve the surface charge density of composite films, which enhances the output performance of the ACF-TENG. The open-circuit voltage (V
OC
), short-circuit current (I
SC
), and transferred charge (Q
Tr
) of the ACF-TENG are about 193.3, 225.4, and 233.3% of those of a pure PP film-based TENG, respectively. Because of the silver in the Ag-zeolite, the ACF-TENG can effectively kill Escherichia coli and fungi. When used in insoles, the ACF-TENG can resist the
athlete's foot
fungus effectively and work as a power source to light up light-emitting diodes and charge capacitors. The ACF-TENG has wide application prospects in self-powered medical and healthcare electronics.
