The magnetoelastic (ME) biosensors are used to detect pathogen in fresh juice or milk by solenoid coil, and also developed for real-time, direct pathogen detection on food surfaces by surface-scanning coil. This paper presents blocking effect of different reagents on non-specific binding for detecting Salmonella typhimurium in apple juice using phage-based magnetoelastic biosensors. Three different blocking reagents of Bovine serum albumin, Superblock blocking buffer and blocker BLOTTO were used and evaluated. The results shows that blocker BLOTTO has the best blocking effect on non-specific binding.
