The Bell Pottinger agency was brought on board following a three-way pitch.
AG Technologies has developed Argent 47, which it claims is the only proven technology to molecularly bind pure silver to fabric.
When incorporated into hospital gowns, sheets and curtains, silver has been proven to combat the growth of bacteria and it is believed it could play a major role in reducing the incidence of hospital-acquired infections.
De Facto will be handling product comms for the company. It will also support the firm with its listing on the London Stock Exchange and will be helping to develop marketing plans for Europe and the Far East.
The account will be headed by De Facto MD Mike Wort and agency co-founder and director Kevin Payne.
De Facto is part of the Bell Pottinger Group. Earlier this year Bell Pottinger announced it was revamping its healthcare offering (PRWeek, 21 March).
Bell Pottinger Health now incorporates De Facto and newly acquired MC Bio-Communications.
