An aqueous ink comprising water, a water-soluble organic solvent and at least two pigments. The aqueous ink is used together with a reaction liquid containing a reactive component that reacts with the aqueous ink to cause aggregation or gelation of the a
Most of the ongoing projects aimed at the development of specific therapies and vaccines against COVID-19 use the SARS-CoV-2 spike (S) protein as the main target. The binding of the spike protein with the ACE2 receptor (ACE2) of the host cell constitutes
