The Promise of Molecular Imprinting...
What is molecular imprinting...
     forming an imprint of a specific molecule
     via plastics beads,
a cast of a molecule,
    or tailor-made polymeric media*.
Some possible uses:
  removing contaminants during manufacture:
    - fungal poison aflatoxin - in food processing
    - during purification of optical isomers
    - removal of unwanted substances in blood
    - removal of cholesterol from solutions
    - as enzyme substitutes (active sites)
    - as sensors to sniff out toxins/pathogens
  detected so far in lab:
           atrazine (a herbicide) & sarin gas
