Summary: When danger is perceived, the human body responds by releasing stress hormones to help overcome obstacles and ensure survival. However, prolonged exposure to stress can lead to health disorders and reduced quality of life. Therefore, it is important to monitor stress biomarkers to quantitatively control stress levels. In this study, a porous sensor composed of PEDOT and COP is developed to detect the stress biomarkers dopamine (DA) and serotonin (5-HT). The sensor exhibits low detection limits and high sensitivity when tested in artificial urine and phosphate-buffered saline. The interaction patterns between the biomarkers and the sensor material are elucidated through theoretical calculations. Overall, the 4l-COP/p electrodes show promising potential as stress sensing devices in healthcare technologies.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.
