Creating and exploring carboxymethyl cellulose aerogels as drug delivery devices.

Carboxymethyl cellulose (CMC) is a well-known cellulose derivative used in biomedical applications due to its biocompatibility and biodegradability. In this work, novel porous CMC materials, aerogels, were prepared and tested as a drug delivery device. CMC aerogels were made from CMC solutions, followed by non-solvent induced phase separation and drying with supercritical CO.

Extraction of bioactive polysaccharide from Ulva prolifera biomass waste toward potential biomedical application.

Ulva prolifera macroalgae blooming caused by water eutrophication seriously affects the marine ecological environment. Exploring an efficient approach to turning algae biomass waste into high-value-added products is significant. The present work aimed to demonstrate the feasibility of the bioactive polysaccharide extraction from Ulva prolifera and to evaluate its potential biomedical application.

Functionalization of nanocellulose applied with biological molecules for biomedical application: A review.

Nanocellulose has great potential in the biomedical field due to its biocompatibility, large specific surface area, and customizable surface chemistry. However, due to the bioinert nature and mismatch of the mechanical strength, nanocellulose itself has no cell adhesion ability and cannot directly promote cell growth and reproduction. Recently, surface functionalization of nanocellulose has been reported as an indispensable strategy for improving its bioactivities or other physic-chemical properties.

Development of Cellulose Nanofibril/Casein-Based 3D Composite Hemostasis Scaffold for Potential Wound-Healing Application.

Excessive bleeding in traumatic hemorrhage is the primary concern for natural wound healing and the main reason for trauma deaths. The three-dimensional (3D) bioprinting of bioinks offers the desired structural complexity vital for hemostasis activity and targeted cell proliferation in rapid and controlled wound healing. However, it is challenging to develop suitable bioinks to fabricate specific 3D scaffolds desirable in wound healing.

Nanocellulose from various biomass wastes: Its preparation and potential usages towards the high value-added products.

Biomass waste comes from a wide range of sources, such as forest, agricultural, algae wastes, as well as other relevant industrial by-products. It is an important alternative energy source as well as a unique source for various bioproducts applied in many fields. For the past two decades, how to reuse, recycle and best recover various biomass wastes for high value-added bioproducts has received significant attention, which has not only come from various academia communities but also from many civil and medical industries.

Current advances and future perspectives of 3D printing natural-derived biopolymers.

3D printing enables the complex or customized structures production in high speed and resolution. However, the lack of bio-based materials with user-defined biochemical and mechanical property is a significant barrier that limits the widespread adoption of 3D printing for products fabrication. Development of eco-friendly natural-derived biopolymers for 3D printing technologies and their promising application in different areas are of huge academic, and environmental interests.
