HUMAN IMMUNODEFICIENCY VIRUS (HIV)-BLOOD INTERACTIONS: SURFACE THERMODYNAMICS APPROACH

HUMAN IMMUNODEFICIENCY VIRUS (HIV)-BLOOD INTERACTIONS: SURFACE THERMODYNAMICS APPROACH ABSTRACT Sequel to the earlier works by Omenyi et al which established the role of surface thermodynamics in various biological processes from the electrostatic repulsion and van der Waals attraction mechanisms, HIV-blood interactions were modeled. This involved the use of the Hamaker coefficient approach as a thermodynamic …
