Nanostructured Calcium Phosphate Dihydrate- Glutaraldehyde Complex as an Innovative Biocidal Film for Anti Sars-Cov-2 Protection of Inanimate Surfaces, Air and a Water Sanitization

Abstract

Glutaraldehyde 2% represents a significantanti-SARS-CoV-2 reference. Blocking one of the 1.5 pent-dial functions with nanostructured Dicalcium Phosphate Dihydrate (DCPD) yields a stable, brick-red compound. Antibiogram tests on the reference bacterial layers of the Institute Pasteur (Algeria) and on resistant bacterial layers of some hospitals confirm that the “calcium phosphate-glutaraldehyde” complex retains the biocidal property. Electron microscopy reveals a porous material while the EDX microanalysis confirms the phosphor-organic structure. The biocidal property and the porous morphology of the material make it possible to consider protective films for inanimate surfaces, air purification filters and water purification filters against SARS-CoV-2 and fragments of viral genetic material.
