Dynamic behaviors on zadaxin getting into carbon nanotubes.
Liu. Ying-Chun YC; Wang. Qi Q
Key Findings
- A carbon nanotube diameter of ~1.9 nm is the minimum size needed for zadaxin to enter.
- The nanotube must also be long enough; too short tubes prevent insertion.
- Low water density favors attraction between zadaxin and the nanotube, while high water density makes the peptide stay with the water.
Practical Outcomes
- For now, this study is mostly theoretical and doesn’t give a direct way to use thymosin‑alpha‑1 at home. It hints that future nanotech carriers could be designed for peptide delivery, but no actionable protocol or dosage advice is available for biohackers today.
Summary
Scientists used computer simulations to see how the peptide thymosin‑alpha‑1 (called zadaxin) can slip into tiny carbon tubes. They found that only tubes about 1.9 nm wide and of a certain length let the peptide enter, and that the surrounding water level changes whether the peptide prefers the tube or the water.
Abstract
The dynamic behaviors of drug zadaxin getting into carbon nanotubes (CNTs) in different water surroundings were investigated by molecular dynamics simulation. It was found that the diameter (1.9 nm) of (14, 14) CNT is the critical size for inserting zadaxin into CNT at the present conditions. In addition, the length of CNTs is another factor for inserting. A certain length is needed. It implies that interactions of zadaxin with both the CNT and the water molecules are competitive in the insertion process. The CNT-zadaxin attractive interaction is found to be the main driving force with the lower density of water molecules in the surroundings, while the zadaxin-water interaction becomes dominant with the higher density. The study of the authors suggests that biomolecules-CNT systems can be further exploited for the potential applications to drugs, vaccines, and gene delivery.
