TOCN/HA复合凝胶的荧光染色

摘要

纳米纤维素作为一种新型的生物质纳米材料，不仅具有天然纤维素可再生、可生物降解等特性，还具有大比表面积、高亲水性、高透明性、高强度、高杨氏模量、低热膨胀系数等优点，已被证明为前景广阔的自组装水凝胶或生物基纳米填料。水凝胶是一类由合成高分子和天然高分子制成的具有三维网络结构的聚合物材料，它能够在短时间内吸收大量液体并且保留液体而不会被溶解。由于其高含水量和高弹性行为，水凝胶被广泛应用于组织填充材料、药物载体、软骨再生、伤口敷料和环境吸附剂等。通过对复合水凝胶的荧光染色，对水凝胶的吸水溶胀及其对生物的毒性的研究。

Fluorescent staining of TOCN/HA composite gel

ABSTRACT

Nanometer fiber as a new kind of biomass, nano materials, not only has the natural cellulose, a renewable, biodegradable and other features, also has a large specific surface area, high hydrophilicity, high transparency, high strength, high young#39;s modulus, low thermal expansion coefficient, etc, has proven to be a broad prospects for the self-assembly of hydrogels or biological nano filler.Hydrogels are a kind of polymer materials with three-dimensional network structure made of synthetic and natural polymers, which can absorb a large amount of liquid in a short time and retain the liquid without being dissolved.Due to its high moisture content and elastic behavior, hydrogels are widely used in tissue filling materials, drug carriers, cartilage regeneration, wound dressings and environmental absorbents.Fluorescent staining of composite hydrogels was used to study the swelling of hydrogels and their toxicity to organisms.

Keywords:Nanocellulose; Water gel; Application; Fluorescent dye
