Herein, we report the in-plane growth of poly(3,4-ethylenedioxythiophene) (PEDOT) thin films and their composites, such as PEDOT-copper (PEDOT-Cu) PEDOT-polythiophene (PEDOT-PT), on a nonconductive substrate by alternating current (AC)-bipolar electropolymerization subsequent use wireless electrodes for generation luminol electrochemiluminescence (ECL). By using gold (Au) wire bipolar electrode (BPE), PEDOT film was initially fabricated exploiting aforementioned electrochemical technique. Successively, fabrication PEDOT-Cu or PEDOT-PT composite accomplished AC-bipolar electrolysis step, where employed BPE to drive cathodic electrodeposition copper particles anodic thiophene, respectively. Additionally, all polymer were further BPEs ECL, which resulted in an intense light emission that could be imaged with common digital camera. Interestingly, have found intensity spatial distribution generated from ECL reaction revealed characteristics different can correlated conductivity composition material.

Cow's milk allergy is one of the most common food allergies in children with a prevalence around 2.5%. Milk contains several allergens; main ones are caseins and β-lactoglobulin (β-LG). At regulatory level, β-LG not explicitly named, but included list substances or products causing intolerances. Hence, presence can be useful marker for determining food. In this work, we present an aptasensor based on electrochemiluminescence (ECL) quantification real matrices displaying integrated advantages consisting high specificity, good sensitivity, portability, cost effectiveness. The performance applicability sensor were tested by analyzing sample skimmed oat-based drink proposed as vegetable substitute animal origin. We obtained linear correlation between intensity signal concentration standard solutions (y = x * 0.00653 + 1.038, R2 0.99). limit detection (LOD) (LOQ) found to 1.36 4.55 μg L-1, respectively.
