The demand for wound care is evolving from 'basic protection' to 'precise repair and efficient healing promotion'. Traditional dressings have difficulty in adapting to the needs of multiple wounds due to poor air permeability and easy adhesion. The emergence of nanocellulose has broken the technical bottleneck and become the core driving force for the upgrade of functional dressings. Nanjing Tianlu Nano Technology Co., Ltd. (hereinafter referred to as 'Tianlu Nano') is deeply involved in this field, using professional technology to promote the industrial application of nanocellulose in functional dressings, helping wound care enter a new stage of 'green and efficient'. Nanocellulose (especially bacterial nanocellulose BNC) has become an ideal substrate for functional dressings due to its high purity, three-dimensional network structure, excellent biocompatibility and degradability. Tianlu Nano focuses on the research and development and large-scale production of nanocellulose core technology and optimizes the preparation process. The nanocellulose substrate fibers it produces are uniform and stable in performance, and can achieve multi-functional modification, driving iterative breakthroughs in functional dressings from the root.

Nanocellulose is a nanoscale functional material prepared from natural cellulose. It has the characteristics of high specific surface area, excellent mechanical strength, good biocompatibility and degradability. In the field of medical and biomaterials, its unique physical and chemical properties make it a core material for promoting clinical treatment, tissue repair and biomedical innovation. Its application scenarios cover wound care, tissue engineering, drug delivery, medical consumables and medical aesthetic care. 1 Wound care field: Accelerated healing 'smart dressing' wound care is one of the earliest medical scenarios where nanocellulose has been industrialized. The core relies on the high purity and three-dimensional network structure of bacterial nanocellulose (BNC). 1.1 Chronic wound and burn care BNC dressing is breathable, moisture-permeable, and can absorb exudate. It can maintain a moist environment on the wound surface, promote cell proliferation and tissue regeneration, and can shorten the healing time by 30% compared with traditional gauze.

Nanocellulose: The road to innovation of green nanomaterials, Nanjing Tianlu helps the industry implement it. Today, with the 'double carbon' strategy in-depth advancement and the concept of environmental protection fully popularized, green materials have become the core direction of industrial upgrading. As a new biomass nanomaterial derived from nature, nanocellulose has broken the limitations of traditional materials with its core advantages of renewable, degradable, and high performance. It has achieved breakthroughs in papermaking, composite materials, biomedicine and other fields, and has become a key force in promoting the green transformation of the industry. As an R&D and industrialization enterprise focusing on the field of nanocellulose, Nanjing Tianlu Nanotechnology Co., Ltd. (hereinafter referred to as 'Nanjing Tianlu') is based in Nanjing. Relying on regional resources and technological advantages, it deeply cultivates this field and promotes nanocellulose from laboratory to large-scale application. It provides professional and efficient green material solutions for various industries and assists the high-quality development of the industry. 1.
