Today, as the biopharmaceutical industry accelerates its transformation to green, safe and efficient, nanocellulose is moving from the laboratory to the forefront of industrialization due to its natural renewable, excellent biocompatibility, complete degradability and other characteristics, becoming a key material to promote innovation in the medical and health field. As a company deeply involved in the field of nanomaterials, we are driven by technological innovation, focus on the biomedical track, and continue to explore the breakthrough applications of nanocellulose in drug delivery, tissue engineering, medical dressings and other fields to provide safer and more efficient solutions for clinical treatment. 1. Nanocellulose: the 'ideal carrier' for biomedicine. Traditional drug delivery systems often face challenges such as low absorption efficiency, poor targeting, and high toxic and side effects. Nanocellulose has become a high-quality carrier for drug delivery due to its unique physical and chemical properties. Its high specific surface area (up to 1000-5000 m²/g) and abundant hydroxyl groups on the surface can be used to chemically modify negative

With the rapid development of precision medicine and regenerative medicine and the increasing consumer demand for safe medical aesthetics and green medical materials, pain points such as biological rejection and residual toxicity of traditional medical materials have become prominent. Nanocellulose (Nanocellulose), which is biocompatible, degradable and high-performance, has become the core choice for the upgrading of biomedicine and medical aesthetics industries. It is used in fields such as wound repair and drug delivery. As a high-tech enterprise deeply involved in the research, development, production and application of nanocellulose, Nanjing Tianlu Nano Technology Co., Ltd. (hereinafter referred to as 'Nanjing Tianlu Nano'), relying on mature technology and large-scale production capacity, is promoting the industrialization of this green nanomaterial in the fields of biomedicine and medical aesthetics, assisting the high-quality upgrade of the industry, and practicing the development concept of 'green empowerment, technology-driven'. Nanocellulose is mainly divided into CNF cellulose nanofibrils, CNC cellulose nanocrystals, and BNC bacterial nanocellulose. The raw materials come from

Under the dual-carbon strategy, green renewable materials have become the core direction of industrial upgrading. Nanocellulose, as a new nanomaterial extracted from natural biomass, has become the key to solving pain points and upgrading the paper industry with its advantages such as environmental protection, high strength, and degradability. Nanjing Tianlu Nanotechnology focuses on the research and development and production of nanocellulose, empowering the high-quality development of the paper industry. Nanocellulose: Definition, Classification and Core Advantages Nanocellulose is a fibrous material that deconstructs natural cellulose to the nanometer scale (1-100 nanometers in diameter) through mechanical, chemical and other processes. The raw material is derived from natural biomass such as wood and straw. It is rich in reserves, green and degradable. It is mainly divided into three categories and is suitable for different application scenarios: • Cellulose Nanocrystal (CNC): High crystallinity, strong rigidity, suitable for high-strength coatings and precision composite materials; • Cellulose nanofiber (CNF): has excellent flexibility and good film-forming properties, and is the most widely used type in papermaking; •
