1. A method for manufacturing a sensor using a screen-printing, the method comprising:
- screen printing hydrophobic ink at a thickness of 5 to 10 μ
m onto a membrane in which a water soluble sample flows to form a pattern comprising multiple channels,whereinthe hydrophobic ink comprises one or more of a silver paste, a carbon paste, a platinum paste, a ceramic paste, or a wax,the hydrophobic ink comprises one or more organic solvents selected from alcohols having 1 to 6 carbon atoms, dimethylformamide (DMF), dimethyl sulfoxide (DMSO), or acetone, andthe membrane comprises one or more of nitrocellulose, nylon, polysulfone, polyethersulfone, or polyvinylidene fluoride (PVDF).
