==Description==we took the UV-vis of HRP from the previous day after it was diluted, 10% HRP and 90% water. We took UV-vis of Cirtrate from august 28. It was already diluted, 10% citrate and 90% citrate.
==Description==
<br> A 2.0 ml solution of luminol, hydrogen peroxide and buffer is prepared. Initial concentration of luminol is 1.46 mM. Initial concentration of hydrogen peroxide is 44.29. Final concentration of luminol, as told by Dr. Hartings, should be 0.126 mM, and concentration of hydrogen peroxide is 50 times luminols, 6.3 mM. Accordingly, 0.17 mL of luminol and 0.28 mL of hydrogen peroxide are added to 1.55 mL of the buffer to make the 2ml solution.

Objective

We are going to test the activity of our HRP-NPs today for the catalytic conversion of luminol

Description

Add experimental record here. Include what, how, and why...

Data

Stock Solution

  1. Buffer
    1. 0.6140g Tris in 1L, pH set to 8 with HCl ---> 5.1mM
  2. Luminol
    1. Dissolve 12.9mg luminol in 300uL of DMSO
    2. Add to 50mL buffer ---> 1.46mM
  3. H2O2
    1. 312uL 30% H2O2 into 100mL buffer ---> Should be 45mM
    2. Check absorption at 250 source (ε(250) = 16.69 M-1cm-1). A = 0.7392. [H2O2] = 44.29mM

Notes

This area is for any observations or conclusions that you would like to note.


Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized.
