'Phytochip': On-chip detection of phytopathogenic RNA viruses by a new surface plasmon resonance platform

► A new SPR platform 'Phytochip' was developed and established. ► It provides an improved detection assay to distinguish virus-infected plants from non-infected plants. ► It has a short detection time and can be used in a high throughput system to analyze efficiently many samples. ► Phytochip is suitable for practical application in plant breeding and virus control.
