aThe biosensor is defined as the nanocellulose material immobilized with the peptide substrate.

bThe specific surface area was determined Brunner Emmett Teller nitrogen or krypton absorption.

cThe sensitivity values reflects the lowest concentration of which the biosensors are able to detect HNE.

dThe surface charge as determined by Zeta potential.
