Fluorescent nanomaterials have attracted much attention,due to their unique luminescent properties and promis-ing applications in biomedical *** this study,lignin basedﬂuorescent nanoparticles(LFNP)with high yield(up to 32.4%)were prepared from lignin nanoparticles(LNP)by one-pot hydrothermal method with ethylene-diamine(EDA)and citric *** and chemical structure of LFNP were investigated by SEM,FT-IR,and zeta potential,and it was found that the structure of LFNP changed with the increase of citric acid *** showed the highestﬂuorescence intensity under UV excitation at wavelengths of 375–385 nm,with emis-sion wavelengths between 454–465 nm,and exhibited strong photoluminescence ***,with the increase of citric acid content,the energy gap(ΔE)gradually decreased from 3.87 to 3.14 eV,which corresponds to the gradual enhancement ofﬂuorescence *** also exhibited excellent antioxidant activity,with DPPH free radical scavenging rate increased from 80.8%for LNP up to 96.7%for LFNP,conﬁrming the great potential of these materials for application in biomedicine and cosmetic health care.

In recent decades,the continuous depletion of fossil fuels and the increasingly serious environmental issue have aroused wide attention on the development of biopolymers based on renewable *** is the second most abundant organic bio-based macromolecule second to cellulose,and it can be widely found in ***,various phenol derivatives can be obtained by their depolymerization *** development of bio-renewable polymeric materials originating from lignin-derivative phenol monomers,such as vanillin,syringaldehyde,eugenol,vanillyl alcohol,vanillic acid,and ferulic acid,will not only valorize the bio-sourced materials but also effectively reduce petroleum resource consumption and mitigate the environmental ***,an updated overview of the synthesis processes of these bio-based polymers developed in the past decade,which includes both thermosets and thermoplastics such as epoxy,phenolic,polyimine,polybenzoxazine,polyurethane,and polyesters,are *** addition,the applications of these bio-based polymers and their composites in flame-retarded materials,degradable and reprocessable materials,dielectric materials,optoelectronic materials,as well as smart responsive materials are also intensively *** line with the gradual development of synthesis technologies,we believe that derivatives of lignin will turn into one of the most promising materials to be considered for the preparation of high-performance and functional bio-based polymer materials.
