- Development of a first-time electrochemical LPS sensor using CNTs and PmB.
- Detection mechanism involves LPS binding to PmB and hindering redox reactions, decreasing peak current.
- CNTs enhance signal through high conductivity and catalytic ability, with PmB providing selectivity.
- Sensor has a wide measurement range of 10 fg/mL to 10 ng/mL.
- High selectivity: no response to other chemicals like human serum albumin, glucose, or bicarbonate.
- Potential applications include water quality management for dialysis fluids and reducing clinical workload.
- Platform can be expanded to detect other targets, indicating broad applicability.
