Fabrication of Environmentally Biodegradable Lignin Nanoparticles

CHEMPHYSCHEM, 13(18), 4235–4243.

By: C. Frangville *, M. Rutkevicius *, A. Richter n, O. Velev n , S. Stoyanov * & V. Paunov *

author keywords: biodegradable; lignin; nanoparticles; pH dependence; porosity
MeSH headings : Biodegradation, Environmental; Chemical Precipitation; Drug Carriers / chemistry; Drug Delivery Systems / methods; Drug Stability; Hydrogen-Ion Concentration; Hydrophobic and Hydrophilic Interactions; Lignin / chemistry; Nanoparticles / chemistry; Particle Size; Polyethylene Glycols / chemistry; Solutions / chemistry
topics (OpenAlex): Lignin and Wood Chemistry; Enzyme-mediated dye degradation; Nanoparticles: synthesis and applications
TL;DR: The study reveals that lignin NPs from the ethylene glycol-based precipitation contain densely packed lignIn domains which explain the stability of the NPs even at high pH, which suggest that these NPs are highly porous and consist of smaller lign in domains. (via Semantic Scholar)
