The EV sheet was fabricated from cellulose nanofibers. The EV capture process from moistened organs using the EV sheet consists of the following steps: EV capture by absorption of ascites on organs, EV storage by drying, washing, and EV release. Then, total RNA was extracted using RNA purification kit (Norgen Biotek Corp, Thorold,  Canada). To obtain tissue RNA, tissues were shredded using the gentleMACS Dissociator (Miltenyi Biotec, Bergisch Gladbach, Germany) and total RNAs was extracted by using the miRNeasy Plus Mini Kit (QIAGEN, Hilden, Germany). Small RNA libraries were prepared using the NEBNext Multiplex Small RNA Library Prep Set for Illumina (New England Biolabs, Ipswich, MA). Then, PCR products were separated by electrophoresis (120 V, 60 min), and DNA fragments corresponding to 140–160 bp (the length of small non-coding RNA plus the adaptors) were recovered.
