Abstract
A multiplexing electrochemical point-of-care biosensing device that provides picomolar level accuracy and high selectivity and which requires only seconds to provide the response. The biosensing device is capable of being mass manufactured due to a molding process used to fabricate the working electrode of the device, which consists of an array of micropillars coated with a biosensitive material.
Claims32
A biosensor comprising:
- an electronics module;
- a sensing module comprising one or more arrays of micropillars coated with one or more biosensitive materials;
- and
- a microfluidic module for routing one or more subject liquids to the sensing module.
1 more element
A method of manufacture of a sensing element of a biosensor comprising:
- creating a mastermold comprising a plurality of arrays of micropillars;
- creating a negative production mold using the mastermold, the production mold comprising a plurality of cavities defining the shape of the arrays of micropillars;
- mixing powdered metal with a binder to yield a slurry;
- placing the slurry into each of the plurality of cavities in the production mold;
- centrifuging the production mold to force the slurry to fill the cavities to yield a plurality of green arrays;
- removing the green arrays from the production mold and
- sintering the green arrays.
