The water beads swelled in the Silver Nitrate solution then they were poured into the Sodium Borohydride solution as the reduction agent.

(a) The procedure of making antibacterial beads. (b) Swelled and dehydrated beads for control and two concentrations of AgNP (c) Effect of AgNP on swelling rate were investigated. (d) Zone of inhibition results with Pseudomonas bacteria.
Antibacterial Beads
Water beads are considered as a superabsorbent polymer (SAP) and the commercial one usually made of Sodium Polyacrylate or Polyacrylamide.
For the water beads project, we decided to make antibacterial water beads for preventing the bacterial growth in the drainage bag. Therefore the CAUTI is controlled by two ways. First, Unidirectional flow and second, inhibition of bacterial growth. Silver nanoparticle (AgNP) were used as the antibacterial agent.
The water beads swelled in the Silver Nitrate (AgNO3) solution then they were poured into the Sodium Borohydride (NaBH4) solution as the reduction agent and finally, dehydrated. Two different concentrations of AgNP were investigated.
Also, an experiment with Agar plate was designed to prove that by using antibacterial water beads, bacterial growth is inhibited.
