Abstract

fetched live from OpenAlex

In this research work, we created and modeled a unique drug protection mechanism employing double-walled carbon nanotubes (DWCNTs) to improve medication stability and delivery efficiency. The research involved the investigation anticancer medication’s shielding of the ZD1694 within seven layers of DWCNTs using molecular dynamics simulations. We aim to investigate the protective effect of DWCNTs by comparing how drug activity is influenced in shielded and non-shielded configurations under mechanical pressure from a gold-tip. The analysis involves computing key structural properties, such as the radial distribution function (RDF) and mean squared displacement (MSD), to evaluate spatial atomic organization and particle mobility. Shielded arrangements show a significant decrease in molecular deformation, with a substantial decrease in MSD (0.872 Å 2 ) compared to unshielded configurations (2.39 Å 2 ). The elastic modulus (EM) and shear modulus (GM) of the DWCNT-shielded system are significantly higher (EM: 3.17×10 -2 GPa; GM: 4.76×10 -2 GPa) compared to the non-shielded system. This indicates an enhanced ability to resist volumetric and shear deformations. These findings open the door for more sophisticated nanobot-based drug delivery systems by proving that DWCNTs can successfully protect medications from mechanical stress, reducing structural disruption and improving stability.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
