Nanomaterials have brought great changes to human society, and development has gradually shifted the focus to environmentally friendly applications. Cellulose nanocrystals (CNCs) are new one-dimensional nanomaterials that exhibit environmental friendliness and ensure the biological safety of water environment. CNCs have excellent physical and chemical properties, such as simple preparation process, nanoscale size, high specific surface area, high mechanical strength, good biocompatibility, high hydrophilicity and antifouling ability. Because of these characteristics, CNCs are widely used in ultrafiltration membranes, nanofiltration membranes and reverse osmosis membranes to solve the problems hindering development of membrane technology, such as insufficient interception and separation efficiency, low mechanical strength and poor antifouling performance. This review summarizes recent developments and uses of CNCs in water treatment membranes and discusses the challenges and development prospects of CNCs materials from the perspectives of ecological safety and human health by comparing them with traditional one-dimensional nanomaterials.

Implant-integrated drug delivery systems that enable the release of biologically active factors can be part of an in situ tissue engineering approach to restore biological function. Implants can be functionalized with drug-loaded nanoparticles through a layer-by-layer assembly. Such coatings can release biologically active levels of growth factors.

In the last few years, cellulose has garnered much interest for its application in drug delivery, especially in cancer therapy. It has special properties like biocompatibility, biodegradability, high porosity, and water permeability render it a good candidate for developing efficient carriers for anticancer agents. Cellulose based nanomaterials like cellulose nanofibers, bacterial cellulose, cellulose nanocrystals and microcrystalline cellulose as delivery vehicles for targeted drug delivery to cancer cells are reviewed.

Conductive hydrogels are an appealing class of "smart" materials with great application potential, as they combine the stimuli-responsiveness of hydrogels with the conductivity of magnetic fillers. However, fabricating multifunctional conductive hydrogels that simultaneously exhibit conductivity, self-healing, adhesiveness, and anti-freezing properties remains a significant challenge. To address this issue, we introduce here a freeze-thawing approach to develop versatile, multiresponsive composite cryogels able to preserve their features under low-temperature conditions.

The effectiveness and safety of hemodialysis can be hindered by protein accumulation, mechanical instability of membranes and bacterial infection during the dialytic therapy. Herein, we show that cellulose acetate membranes modified with the low-fouling polymers (namely polyvinylpyrrolidone and polyethylene glycol), followed by the in situ reduction of different densities of silver oxide(I) nanoparticles, can effectively address these limitations. These improvements comprise the enhanced resistance to the protein fouling, improved antimicrobial capabilities against S.
