Recommended Potentiostat
A compact, research‑grade potentiostat was identified as a suitable platform for electrochemical biosensor development, supporting standard techniques such as cyclic voltammetry, pulse methods, and amperometry while maintaining sensitivity at low current levels.

This instrument is designed for seamless integration with screen‑printed electrodes and is widely used in biosensing and diagnostic research.
Screen‑Printed Electrode Options
To support assay optimisation and comparison of surface chemistries, two electrode materials were recommended.
Carbon Screen‑Printed Electrodes
Carbon electrodes provide a robust and cost‑effective platform for early‑stage biosensor development and routine electrochemical measurements.
- Carbon 501 Sensor Cartridge Pack (100 electrodes)

These electrodes are commonly used for enzyme‑based and redox‑mediated assays and perform well in complex biological matrices.
Gold Screen‑Printed Electrodes
Gold electrodes were also recommended for applications requiring controlled surface functionalisation, such as antibody or aptamer immobilisation.

Gold SPEs are particularly well suited to affinity‑based hormone detection strategies.
Supporting Accessories for Reliable Measurements
To ensure consistent and reproducible electrochemical performance, appropriate electrode preparation was also highlighted as an important part of the workflow.

These accessories help maintain electrode surface quality, particularly when working with biological samples such as blood or plasma.
A Flexible Path to Procurement
By offering both direct quotation via the sales team and immediate purchase through the online webstore, researchers can choose the route that best fits their project timelines. This flexibility allows rapid transition from technical discussion to hands‑on experimentation.
Together, this combination of potentiostat, electrodes, and accessories provides a complete and adaptable foundation for electrochemical hormone biosensor development.
