Ref.
Amperometric
glucose
biosensor
Pt electrode
GOD was entrapped into the polypyrrole (PPy) fi lm
during an electrochemical polymerization process
11
Screen-printed
Ag-carbon strip
two-electrode
GOD was covalently immobilized in the membranes
prepared by condensation of both β-cyclodextrin
polymer (β-CDP) and carboxymethylated
β-cyclodextrin polymer (β-CDPA)
12
Pt electrode
GOD was dropped onto the Pt/(CHIT/PAA)
n
layer, and
then chitosan solution was placed on the surface; after
being dried at room temperature, glutaraldehyde (GA)
slowly spread over the chitosan fi lm
13
Glassy carbon
electrode (GCE)
GOD was immobilized on the negatively charged surface
of carbon nanotubes (CNTs) by alternatively
assembling a cationic polydiallyldimethylammonium
chloride (PDDA) layer and a GOD layer
14
Ni electrode
GOD was immobilized by a glutaraldehyde (GA)/bovine
serum albumin (BSA) cross-linking procedure on the
surface of an alkali nickel hexacyanoferrate thin fi lm
15
Cu-dispersed
ceramic-graphite
biocomposite
electrode
GOD was immobilized into a copper-dispersed sol-
gel-derived ceramic-graphite composite
16
Pt electrode
GOD was entrapped in a polyacrylamide microgel
17
Screen-printed
electrode
GOD was genetically modifi ed by adding a polylysine
chain at the C-terminal with a peptide linker inserted
between the enzyme and the polylysine chain
18
Indium-tin oxide
(ITO)-coated glass
electrode
GOD was immobilized in layer-by-layer (LbL) fi lms,
adsorbed alternately with poly(allylamine)
hydrochloride (PAH) layers
19
Nanoelectrode array
(NEA) Pt electrode
GOD was immobilized on the NEA electrode by a
physical adsorption
20
Pt electrode
GOD was immobilized into a poly(
o
-phenylenediamine)
(POPD) fi lm by simple one-step electropolymerization
procedure
21
Ink-printed gold fi lm
electrode
GOD was modifi ed with ferrocene derivatives as the
electron transfer mediator
22
Pt electrode
GOD was immobilized in a PPy layer on the electrode
23
GCEs modifi ed by
processible
polyaniline (PANI)
GOD was suspended by 0.25-0.3% neutralized Nafi on,
and the complex was syringed onto the surface of the
electrode
24
Optical

2
GOD was immobilized on a bamboo inner shell
membrane with GA as a cross-linker
26
Spectrophotometer
GOD was linked onto Prussian blue (PB) fi lm
chemically
27
Optical oxygen
transducer
GOD was entrapped within the xerogel that was derived
from tetraethylorthosilicate and hybridized with
hydroxyethyl carboxymethyl cellulose polymer
