| contents | The development of statistical physics in Africa is in its nascent stages, yet its application holds immense promise for advancing emerging research trends on the continent. This perspective paper, a product of a two-week workshop on biophysics in Morogoro (Tanzania), aims to illuminate the potential of statistical physics in regional scientific research. We employ in-silico atomistic molecular dynamics simulations to investigate the loading and delivery capabilities of lecithin nanolipids for niclosamide, a poorly water-soluble drug. Our simulations reveal that the loading capacity and interaction strength between lecithin nanolipids and niclosamide improve with increased lecithin concentrations. We perform a free-energy landscape analysis which uncovers two distinct metastable conformations of niclosamide within both the aqueous phase and the lecithin nanolipids. Over a simulation period of half a microsecond, lecithin nanolipids self-assemble into a spherical monolayer structure, providing detailed atomic-level insights into their interactions with niclosamide. These findings underscore the potential of lecithin nanolipids as efficient drug delivery systems. |
