Multifunctional biosensors redefining liquid biopsy: advancing simultaneous multianalyte detection Liquid biopsy has revolutionized noninvasive disease diagnosis and monitoring by detecting circulating biomarkers such as tumor-derived DNA, miRNAs, proteins, exosomes, and circulating tumor cells in body fluids. Conventional single-analyte approaches fail to capture disease complexity, limiting diagnostic accuracy. Multifunctional biosensors enable simultaneous detection of multiple biomarkers, representing a paradigm shift in liquid biopsy. This review highlights recent advances in diverse detection strategies, including optical, electrochemical, plasmonic, and clustered regularly interspaced short palindromic repeatsโ€“based assays, alongside innovations in hybrid platforms, smart surface engineering, and nanotechnology. We also discuss integration with microfluidics, artificial intelligence, and chemometric analysis to enhance sensitivity, reduce signal interference, and improve scalability. Finally, challenges in clinical translation and standardization are highlighted, underscoring the transformative potential of multifunctional biosensors in precision medicine and early disease detection.

Two-photon voltage imaging with rhodopsin-based sensors Rhodopsin-based GEVIs were thought to lose voltage sensitivity with two-photon excitation, limiting their utility for deep in vivo imaging. We introduce Jarvis, a bright and photostable GEVI, and demonstrate that, along with pAce and Voltron2, it enables high-contrast two-photon voltage imaging and AP detection at kilohertz rates.
