Nanoparticle biofabrication using English ivy (Hedera helix)

Area of Science:

• Plant Biology
• Nanotechnology
• Biomaterials

Background:

• English ivy (Hedera helix) produces unique organic nanoparticles (60-85 nm) in its root hairs, crucial for its adhesive properties.
• These plant-derived nanoparticles show potential for biomedical and cosmetic uses, offering a safer alternative to metal oxide nanoparticles.

Purpose of the Study:

• To develop an enhanced system for producing adventitious roots and their associated organic nanoparticles from English ivy.
• To optimize conditions for maximizing nanoparticle yield and establish a plant-based nanomanufacturing platform.

Main Methods:

• Juvenile English ivy shoot segments were cultured in modified GA7 Magenta boxes.
• Optimal adventitious root production was achieved using a 4-hour application of 1 mg/ml indole-3 butyric acid (IBA).
• Nanoparticle morphology was characterized using atomic force microscopy.

Main Results:

• The optimized system yielded 90 mg of dry weight nanoparticles per 12 g of roots.
• Nanoparticle morphology was consistent with previous findings.
• The study successfully established a method for culturing and harvesting plant-based nanoparticles.

Conclusions:

• An improved system for English ivy adventitious root and nanoparticle production was developed.
• This represents the first platform for growing and harvesting organic nanoparticles from plants, advancing plant-based nanomanufacturing.
• The system provides a pathway for generating bulk ivy nanoparticles for biomedical applications.
