COVID-19 virus has positive electrical charges. So, particles that are negatively charged would, by opposite charges-electrostatic attraction, inhibit its replication's first stage (attachment to cells) and mop its extra-cellular particles. Positively charged particles would similarly mop/destroy cells it infects because unlike healthy cells which are neutral, infected/tumor cells have negative electrical charges. Nanoparticles (0.96 nm) of Aluminum-magnesium silicate (AMS), WHO-approved medicine/adjuvant have both negative and positive charged ends. As adjuvant it improves antimicrobials' efficacies (clearing secondary infections) while as silicate it enhances immunity. By inhibiting viral replication; mopping extra-cellular viruses/abnormal cells; clearing secondary infections; enhancing immunity, AMS terminates viral-infections/abnormal cells' metastases. Natural AMS has impurities and its deposits are not found in Nigeria. So, Aluminum silicate and Magnesium silicate (WHO-approved medicines) were used for Medicinal synthetic AMS {MSAMS: Al 4 (SiO 4 ) 3 + 3Mg 2 SiO 4 → 2Al 2 Mg 3 (SiO 4 ) 3 }. Since AMS is un-absorbable, dextrose monohydrate is incorporated in MSAMS-formulations to convey its Nanoparticles into blood for circulation to all organs/tissues (active-transportation). The MSAMS achieved quick cure (within 3 days) of all four COVID-19 patients used for its first-phase trial (one in Nigeria, two in Cameroon, one in Tanzania).
