Abstract
The present disclosure relates to the manufacture and use of redox electrodes and their use in cell lysis. In certain embodiments, the redox electrodes are manufactured using a hybrid material approach, such as using a redox polymer in combination with a support substrate, such as cellulose fibers or paper. In certain implementations, the redox electrodes are suitable for use at voltages greater than 25 Volts.
Claims24
An oxidation-reduction (redox) electrode, comprising:
- a support substrate comprising one or more of particles or fibers;
- and
- a redox polymer combined with the support substrate particles or fibers and having a thickness greater than 1 micron with respect to the surface of the support substrate.
A method for manufacturing a redox electrode, comprising:
- blending an aqueous dispersion of a redox polymer with cellulose fibers to form a slurry;
- solution casting the slurry into one or more molds each having a form factor corresponding to the redox electrode to form a respective redox electrode in each mold;
- and
- recovering the respective redox electrode from each mold.
A method for manufacturing a redox electrode, comprising:
- dip coating a cellulose paper substrate in an aqueous dispersion of a redox polymer one or more times;
- and
- forming the redox electrode using the dip coated cellulose paper.
A method for manufacturing a redox electrode, comprising:
- solution casting an aqueous dispersion of a redox polymer onto a cellulose paper substrate;
- and
- forming the redox electrode using the solution cast onto the cellulose paper.
