The detection of chloramphenicol (CAP) is of paramount importance in safeguarding food safety and protecting human health. Herein, a photochemical (PEC) electrode combined with CAP molecular imprinted (TiO 2 -MIPC) films has been reported and then the PEC property has been utilized to realize light-elution function. The PEC theory has been used to accelerate the preparation of MIPs combined with special recognition of MIPs to enhance PEC sensors and their detection capacity. The SEM image shows that MIP films were deposited on a pipe orifice of the TiO 2 . The TiO 2 -MIPC sensor electrode exhibits high selectivity and sensitivity for determination of CAP, and the differential pulse voltammetry (DPV) analysis is highly linear over CAP concentrations of 0.1−20 ng/mL with a detection limit of 0.03 ng/mL (S/N = 3). Moreover, DFT calculations indicate that the combination mode of PANI@CAP may be hydrogen-bond interactions between amino and nitro groups, and the P/N junction of PEC-MIPC generates photogenic charge to break the hydrogen bond as well promote the self-elution function. Thus, this convenient and sensitive PEC sensor will improve the efficiency of hazardous substance detection and offer a design for future PEC sensors.

This study presents a novel multimodal cancer theranostic platform developed using tumor cell‐coated biomimetic carbon nanohorn (CNH) complexes that encapsulate the anticancer drug paclitaxel (PTX). This platform combines photothermal therapy, chemotherapy, and immunotherapy to fight against malignant colorectal cancer. These engineered nanocomplexes are designed to deliver sufficient PTX molecules into a targeted solid tumor in a light‐controllable manner while inducing significant photothermal and antitumor immune responses. The outstanding photothermal conversion property of the CNHs under near‐infrared light enables effective cancer cell ablation and awakening of cytotoxic immune responses. Tumor cell membrane‐coated CNHs show improved water dispersibility, immune evasion, and targeting capabilities alongside enhanced immune activation against tumors. The efficacy of the biomimetic functional CNH nanocomplexes is demonstrated through excellent tumor‐targeting, controlled drug‐releasing behavior, and induction of cancer cell death, contributing to a robust antitumor response. This study provides a promising approach to cancer treatment by integrating multiple therapeutic modalities into a single platform, potentially enhancing treatment efficacy to combat intractable cancer.
