The disclosure relates to two methods to modify microneedles and needles to transform them as electrochemical sensors for ions and biomolecules. The methods focus on microneedles and needles made of any material through an external and internal modification methods to provide the function as electrodes: the working electrode, (pseudo)counter electrode and/or (pseudo)reference electrode depending on the electrochemical readout. With the external modification method, any solid microneedle and needle can be individually transformed in either of the said electrodes. With the internal modification method, any hollow microneedle and needle can be individually transformed in either of the electrodes. The working electrode, (pseudo)counter electrode and or (pseudo)reference electrode can be simultaneously integrated into the same hollow microneedle or needle by internal compartmentation. Two different biofluids can be simultaneously targeted by microneedles and needles of different sizes, structures and fabricated by one or both methods when integrated in the same skin patch.
