Summary: This article reports a method for preparing cellulose nanofiber (CNF) dry powders that can be redispersed with water while maintaining high transparency, viscosity, and controllable viscosity based on the shear rate. Dehydration and vaporization procedures are discussed to prepare dry powders without the use of additives. Dry powders prepared by boiling exhibit transparency but do not recover their initial viscosity, while freeze-dried powders fully recover all their initial properties but have a larger volume that does not reduce transportation and storage costs. Evaporative dry powders from solvent-exchanged CNF organogels fully recover all their properties and have small volumes and good handling, contributing to the reduction of transportation and storage costs.

Summary: In this study, cellulose nanofiber (CNF) sheets were used to capture and preserve extracellular vesicles (EVs) for analysis of bioactive molecules inside EVs. The results showed that CNF sheets allowed for the detection of cancer-associated miRNAs in the early phase of ovarian cancer, even before the appearance of ascites. Furthermore, EVs from different locations exhibited unique miRNA profiles, and location-based differences in EV miRNA profiles were identified in patient samples, reflecting disease conditions. Spatial exosome analyses using CNF sheets revealed location-dependent heterogeneity of ascites EVs from cancer patients.
