Abstract:lignin nanoparticles possess advantages of both nano-scale material and natural lignin properties， thus have a wide range of applications. The mechanical methods （including high-pressure homogenization， ultrasonic treatment and combined methods）， nano-precipitation methods （including self-assembly， acid precipitation and dialysis）， interfacial cross-linking and emulsion methods， and biological preparation methods were reviewed in this paper. The application progress in antibacterial， anti-oxidation， ultraviolet protection， drug delivery， nanocomposite， catalysis and strain sensor were summarized. In addition， the outlook of development direction of lignin nanoparticles was proposed. As a new way of comprehensive application of pulping black liquor， lignin nanoparticles had great potential for future applications.
