Summary: C-dots are a new class of materials with various applications, and the synthesis of bio-based C-dots has gained increasing attention. Polysaccharides, as the most abundant natural materials, have been focused on for the synthesis of C-dots due to their high biodegradability and non-toxicity. C-dots obtained from polysaccharides are usually fabricated through thermal procedures, carbonization, and microwave pyrolysis. The important properties of C-dots include small size, photo-induced electron transfer (PET), and highly adjustable luminosity behavior.

Summary: As industrialization has increased, new methods of oil-water separation are needed to address the prevalence of oil-water mixtures on Earth. Mechanically refined cellulose nanofibrils (CNFs), as a renewable resource with high barrier properties, show promise for oil-water separations. Lignin-containing CNFs (LCNFs), the unbleached form of CNFs, also display extraordinary barrier properties and offer more cost-effective and environmentally friendly options. Wet and dry LCNF-modified filter papers were developed using vacuum filtration, and it was found that the addition of LCNF improves oil separation efficiency, with wet filters showing better performance than dry filters at the same LCNF coat weight.

Summary: Nanofibrillated bacterial cellulose (NFBC) was modified with an aqueous alkaline solution of 2,3-epoxypropyltrimethylammonium chloride (EPTMAC) to confer it with antimicrobial properties. The modified NFBC showed similar fiber morphologies and crystal structures to pristine NFBC, indicating that EPTMAC selectively reacted with the surface hydroxyl groups of NFBC. The modified nanofibers demonstrated antibacterial activity against Klebsiella pneumoniae, likely due to the positive charge on the surface of the modified NFBC.

Summary: A novel colorimetric test paper for metal ions detection was developed based on functionalized cellulose fibers, showing robust mechanical property, thermal stability, selectivity, and rapid response to Fe3+ and Cu2+ ions. The mechanism involved the coordination chelation of acetoacetyl groups with metal ions to form a six-membered ring structure, leading to a noticeable color change within 5 seconds. This method provides a facile and universal approach to prepare efficient and portable cellulose-based test paper, showing great potential in the field of metal ion detection.
