Efficient utilization of lignocellulosic residues from forestry and agriculture is a critical challenge for sustainable resource management. Conventional cellulose nanofibers often require intensive delignification and purification, leading to high energy consumption and loss of natural functionalities. Lignin containing cellulose nanofibers (LCNFs), produced by partially retaining functional lignin within the cellulose framework, have emerged as a promising alternative. This review systematically summarizes the structural features, preparation strategies, and functional properties of LCNFs. The design of LCNF-based functional materials is further discussed, highlighting how their hierarchical structures and lignin-cellulose interactions govern the structure-performance relationship across applications in flexible electronics, environmental remediation, personal protection, and biomedicine. By emphasizing these mechanistic links, this review provides insightful guidance for the design and development of high-value, sustainable LCNF-based materials.

02:22Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.
01:56Structural Protein Function
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...

01:29Structure and Function of Erythrocytes
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...
01:18Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
