5.000 g of THPS was placed in a 50 mL centrifuge tube, and 2 mL of 15% (w/v) potassium ferrocyanide and 2 mL of 30% (w/v) zinc sulphate were added with slow stirring and the volume made up with distilled water.
Briefly, PBNPs were prepared by slowly adding 20 mL of a 1.0 mMFe(III) chloride (anhydrous) (Fe[Cl.sub.3]) (Sigma-Aldrich) solution containing 0.5 mmol of citric acid (Sigma-Aldrich) to a solution containing an equimolar amount of potassium ferrocyanide (anhydrous) ([K.sub.4][Fe[(CN).sub.6]]) (Sigma-Aldrich) under rigorous stirring at 40[degrees]C.

Then, 2 ml potassium ferrocyanide solution (0.25 M) was added to the extract, which was mixed and left for 5 min.
9mL of Ultrapure water (UPW) water (with 0.1% formic acid) was added followed by 0.5 ml of Carrez I (potassium ferrocyanide) and 0.5 ml Carrez II (zinc acetate).
The GOx immobilized on the anode surface reacts with glucose to produce protons and electrons while the incoming electrons moving from the anode to the cathode electrode via the external circuit decrease the ferricyanide ([Fe[CN].sub.6.sup.3-]) to ferrocyanide ([Fe[CN].sub.6.sup.4-]).
Prussian blue (PB, ferric ferrocyanide), formula [Fe.sub.4] [[Fe[(CN).sub.6]].sub.3], is a microcrystalline blue powder.
Baker (Thailand), phosphate buffer saline (PBS, pH 7) was obtained from Merck (Germany), and potassium ferricyanide ([K.sub.3][Fe[(CN).sub.6]]) and potassium ferrocyanide ([K.sub.4][Fe[(CN).sub.6]]) were obtained from Bendosen (Bendosen Laboratory Chemicals, Bendosen, Norway).
1 mm long segments of the optic nerve 1.5 mm distal to the lesion site were immersion-fixed in 2.5% glutaraldehyde for 2 h, washed in 0.1 M cacodylate buffer (pH 7.4), and postfixed for 1 h in 1% (wt/vol) osmium tetroxide containing 0.8% potassium ferrocyanide and 5 nM calcium chloride in 0.1 M cacodylate buffer (pH 7.4).
After fixation, the tissues were post fixed in a mixture of 1% osmium tetroxide and 1.5% potassium ferrocyanide, dehydrated, embedded in Epon and sectioned for electron microscopy.
This reduction is readily observed by change in the absorption maximum of potassium ferricyanide [K3Fe(CN)6], since it is reduced to potassium ferrocyanide [K4Fe(CN)6] by the CME which is then converted into ferri ferrocyanide Fe4[Fe(CN)6]3 in the presence of FeCl3.
Ferricyanide (Fe[(CN).sub.6.sup.3-]) and ferrocyanide (Fe[(CN).sub.6.sup.4-], 1mM each in 0.1 M potassium nitrate (KN[O.sub.3]), [E.sup.0'] = 0.189 V versus SCE) served as the charge-transfer probe.
