Luminol was combined with additives in an attempt to remove or minimize reactivity with bleach while maintaining the chemiluminescent reaction with blood. By visually observing the reaction, as would be done in a crime scene, the amount of inhibition was determined. Additives were discovered that ...
Blood's reaction to luminol is a very dull fluorescence of light blue. The handprint on the cover is much brighter than what crime scene photographers are normally accustomed to when fluorescing blood with luminol. The image on the cover was produced by spraying luminol on a handprint made ...
with a drop of blood. The blood must be on the alcohol pad. The forensic test is for dried or latent blood, so the reaction between the alcohol and fresh blood is necessary. Notes About the Luminol Test In addition to iron and iron compounds, other substances can catalyze the luminol ...
The synthesis of Luminol is as follows: To a reaction tube, add 140 mg of 3-nitrophthalhydrazide and 1.0 mL of 3 M sodium hydroxide solution. Stir with a rod, and to the resulting deep brown-red solution add 0.6 g of sodium hydrosulfite dihydrate (Na2S2O4 · 2 H2O, MW 210.2). Wash...
In some cases, luminol leads investigators to more evidence. For example, if luminol detects trace amounts of blood on a carpet, investigators may pull up the carpet and discover a lot of visible blood on the floorboards below. One problem with luminol is that the chemical reaction can destr...

The synthesized HRP/GOx-luminol-GO could react with H 2 O 2 generated from GOx catalyzed glucose oxidization reaction, to produce strong CL emission in the presence of co-immobilized HRP. Thus, we developed an ultrasensitive, homogeneous, reagentless, selective, and simple CL sensing system for...
The method is based on the inhibition by SOD of the chemi luminescence signal produced in the reaction between luminol and horseradish peroxidase (HRP) which liberates superoxide anion. The peak value of the chemi luminescence produced in the reaction is linearly related to the HRP concentration ...

A new flow injection chemiluminescence method based on the quench effect of kaempferol on the chemiluminescence reaction between luminol and H2O2 under alkaline conditions was developed for the determination of kaempferol.Under optimized conditions,the decrease of chemiluminescence intensity was linear with ka...
