Biosensors Journal is one of the most accessed journals on biosensors in free radical scavenging. All published articles are assigned to Digital Object Identifier (DOI) CrossRef and are freely accessed using Google Scholar. The journal focus on current trends and developments and topics such as biosensor applications for environmental and water monitoring, agro-industry applications, and trends in the detection of nerve agents and pesticides.
A method for the electrochemical detection of antioxidants has been developed, which is based on a radical measurement with a cytochrome c modified electrode. A controlled enzymatic production system for superoxide radicals based on xanthine oxidase was used. The addition of antioxidants facilitated the decomposition of the radical in addition to the spontaneous dismutation. The steady-state of superoxide generation and decomposition was thus shifted to a new situation due to the higher decomposition rate after antioxidant addition. This resulted in a decreased current level at the electrode. Antioxidant activity could be quantified from the response of the sensor electrode by the percentage of the signal decrease.
OMICS Group is built upon the principles of Open Access and is determined to provide free and unrestricted access of research articles to scientists around the world for the advancement of science and technology. Submitted articles in the Biosensors Journal avail open accessing. OMICS special features include 21 Day rapid review process and an eminent team of 50,000+ editorial board members and 50,000+ Reviewer team. Open Access initiative helps in unlocking the traditional methods of subscription articles and releasing information to tertiary level readers, who normally would not have access to first hand research studies.
