Coordination-Induced Photocurrent Polarity Switching of Black Titanium Dioxide for Tyrosinase Activity Assay

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Май 4, 2025

Polarity-switchable photoelectrochemical (PEC) analysis has garnered significant attention owing to its enhanced accuracy and superior anti-interference capability. Developing a straightforward efficient approach for polarity-switchable PEC is critically essential. We present here novel assay by leveraging the coordination interactions between black titanium dioxide (b-TiO2) o-diphenol-functionalized BiOI. Specifically, 4-hydroxyphenylacetic acid was covalently functionalized onto hydrolyzed 3-aminopropyl triethoxysilane-modified BiOI nanosheets, monophenol groups on are further converted into o-diphenol through tyrosinase (TYR) catalysis. Consequently, nanosheets attached b-TiO2-based photoelectrode via b-TiO2 groups, enabling photocurrent polarity switching of electrode TYR activity. The developed activity exhibits broad linear range from 0.010 10 U mL-1 low detection limit 0.002 mL-1. work not only reports an innovative switchable strategy but also establishes effective method assay.

Using BiOI/BiOCl Composite-Enhanced Cathodic Photocurrent and Amplifying Signal Variation in AgI for Developing a Highly Sensitive Photoelectrochemical Immunosensing Platform

Chemosensors, Год журнала: 2025, Номер 13(5), С. 164 - 164

Опубликована: Май 5, 2025

Photoelectrochemical (PEC) sensors have emerged as potential analysis techniques in recent years due to PEC’s benefits, which include straightforward operation, quick response times, and basic equipment. In this work, a new PEC sandwich immunoassay was fabricated, based on low-toxicity BiOI/BiOCl composites accompanied by enhanced signal detection via AgI-conjugated antibodies (Ab2-AgI). Specifically, the inorganic semiconductor were first utilized bioanalysis. Owing unique configuration of energy levels between BiOI BiOCl, photoelectric more excellent than those or BiOCl alone. Moreover, Ab2-AgI conjugates amplification components through specific antibody–antigen immunoreaction. presence target Ag, immobilized clearly improve steric hindrance sensing electrode effectively hinder transfer photo-induced holes; meanwhile, AgI NPs can competitively absorb excitation light. A immunosensing platform for detecting tumor markers at 0 V under visible light developed, using carcinoembryonic antigen (CEA) model analyte demonstrated an ultra-low limit 4.9 fg·mL−1. Meanwhile, it specificity stability, potentially opening up novel promising other critical biomarkers.
