| Abstract | In this research, a reproducible surface plasmon resonance (SPR) immunosensor based on inhibition format was fabricated for stable and sensitive detection of four sulfonamides (SAs) in animal-derived foods. The parameters in the fabrication and measurement process were optimized and discussed in details. The method using the proposed SPR immunosensor was validated and exhibited favorable performance for SAs residues detection in common animal-derived food products, as well as acceptable accuracy (pure milk 88.5–106.2%; egg 89.0–91.5%; chicken muscle 87.2–94.7%; beef 84.8–96.9%; fish 87.8–95.0%), precision (relative standard deviation (n = 3), pure milk 3.2–5.2%; egg 1.1–5.4%; chicken muscle 1.1–5.9%; beef 2.5–7.1%; fish 4.6–5.3%), and sensitivity (IC$_{15}$, pure milk 59.6 ng mL$^{−1}$, egg 56.1 ng mL$^{−1}$, chicken muscle 66.9 ng mL$^{−1}$, beef 63.3 ng mL$^{−1}$, fish 62.7 ng mL$^{−1}$ ). Each detection cycle could finish in less than 5 min, and each SPR chip could reuse 300 analysis cycles with response attenuation of 3.7%. These results have demonstrated that the proposed SPR immunosensor has offered an effective, accurate, sensitive, rapid, and low-cost methodology for SAs residue detection in food sample, and this method has great potential for the routine analysis of large numbers of samples on measuring different kinds of compounds. |

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.
