Overview

This research demonstrates lignin nanoparticles' antibacterial, antioxidant, and UV-absorbing effects in lignocellulosic biomass, suggesting sustainable applications.

Key Points

This work aimed to extract and synthesize lignin nanoparticles with effective antibacterial, antioxidant, and sunscreen properties from Oxytenanthera abyssinic.
Extracted soda lignin from Oxytenanthera abyssinic stems using alkaline treatment.
Applied a 1, 4-dioxane-based nanoprecipitation technique for self-assembly of lignin nanoparticles.
Optimized extraction through temperature (23–120°C), time (1–24 hours), and NaOH concentration (5–15%).
Conducted functional evaluations including DPPH assays for antioxidant activity, SPF measurements, and antibacterial testing against Gram-positive and Gram-negative strains.
Produced up to 294 mg/g of soda lignin with OA-LNPs showing a size range of 65 to 135 nm.
OA-LNPs exhibited a zeta potential of -30.1 mV and maintained essential phenolic functionalities.
Antioxidant activity of OA-LNPs was 11.47 µg/mL, significantly better than soda lignin's 131.1 µg/mL.
SPF measurements of commercial lotions improved by adding OA-LNPs, reaching 114.8±1.3.
Moderate antibacterial efficacy demonstrated with inhibition zones between 12.43±0.90 to 28.8±1.11 mm.
