| Abstract | Multi-walled carbon nanotubes decorated with Fe3O4 nanoparticles (Fe3O4NPs/MWCNTs) were prepared and used to fabricate an electrochemical sensor for the determination of enrofloxacin. The electrochemical response of the carbon paste electrode (CPE) modified with Fe3O4NPs/MWCNTs towards enrofloxacin was investigated by cyclic voltammetry and differential pulse voltammetry. The results indicated a remarkable growth in the oxidation peak current together with negative shift in the oxidation peak potential for enrofloxacin, in comparison to both the unmodified CPE and the CPE modified with MWCNTs (MWCNT/CPE). The prepared sensor displayed a rapid and sensitive response towards enrofloxacin, which was attributed to the synergetic electrocatalytic effect of Fe3O4NPs and MWCNTs. The sensitivity enhancement with nearly three orders of magnitude (0.3–100 μM) was gained, compared with the MWCNT/CPE, with a detection limit of 0.09 µM (S/N = 3). The proposed method was successfully applied for the highly sensitive determination of trace amounts of enrofloxacin in cow's milk, egg, honey and chicken samples. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
