Other claims from this paper (12)
- Intervention effect Both gold nanomaterials induced B. xylophilus immobilization in a concentration- and time-dependent manner in vitro.
- Intervention effect 0.5 mg/L His-AuNCs caused about 70% nematode immobility after 48 hours.
- Intervention effect 0.5 mg/L PEI-AuNPs caused over 75% nematode immobility after 48 hours.
- Observation Both nanoparticles were internalized by B. xylophilus and accumulated in internal tissues, particularly the anterior and intestinal regions.
- Intervention effect Stem injection of either nanomaterial at 0.05 mg/L delayed symptom onset in pine seedlings.
- Intervention effect Stem injection of either nanomaterial at 0.05 mg/L reduced disease severity in pine seedlings.
- Intervention effect Stem injection of either nanomaterial at 0.05 mg/L preserved vascular integrity in pine seedlings.
- Intervention effect His-AuNCs downregulated genes related to cuticle formation and metabolism in the nematode.
- Intervention effect PEI-AuNPs induced a focused stress response in the nematode, primarily upregulating heat shock proteins.
- Intervention effect Both gold nanomaterials showed minimal acute toxicity in zebrafish assays.
- Method / resource Green synthesis of His-AuNCs yielded monodisperse particles of 1.36 ± 0.05 nm with a zeta potential of -19.2 ± 0.3 mV.
- Method / resource PEI-AuNPs were uniform spherical particles with a hydrodynamic diameter of 11.18 ± 0.9 nm.
