The scientists suggest using phage therapy (using bacteriophages) to target the bacterial infection. Compared to chemical pesticides, phages only specifically attack the targeted bacterial species, leaving other cells unharmed. Unlike chemical pesticides, phages are biodegradable and do not accumulate in the environment.

The key to the phage attacking the bacteria is it's specific recognition of the bacteria via the receptor. 

Considering that there are proteins involved in this reaction, suggest atleast 2 intermolecular forces that help the phage bind to the bacteria.
