“…Gold nanorods (AuNRs) functionalized by antibodies have been used to detect Cymbidium mosaic virus (CymMV) or Odontoglossum ringspot virus (ORSV) for rapid diagnosis of viral infections. The limits of detection (LODs) for CymMV and ORSV were reported to be 48 and 42 pg/mL, respectively, in leaf saps [ 95 ]. The detection of CymMV and ORSV was not only reported by SPR technique, but also by QCM technique.…”

Food losses due to crop infections from pathogens such as bacteria, viruses and fungi are persistent issues in agriculture for centuries across the globe. In order to minimize the disease induced damage in crops during growth, harvest and postharvest processing, as well as to maximize productivity and ensure agricultural sustainability, advanced disease detection and prevention in crops are imperative. This paper reviews the direct and indirect disease identification methods currently used in agriculture. Laboratory-based techniques such as polymerase chain reaction (PCR), immunofluorescence (IF), fluorescence in-situ hybridization (FISH), enzyme-linked immunosorbent assay (ELISA), flow cytometry (FCM) and gas chromatography-mass spectrometry (GC-MS) are some of the direct detection methods. Indirect methods include thermography, fluorescence imaging and hyperspectral techniques. Finally, the review also provides a comprehensive overview of biosensors based on highly selective bio-recognition elements such as enzyme, antibody, DNA/RNA and bacteriophage as a new tool for the early identification of crop diseases.

“…The combination of the optical properties of gold nanostructures-LSPR surfaces with the achievement of total internal reflection via optical fiber configurations can provide signal enhancement and better spatial sensitivities. The integration of nanorod-modified surfaces into a fiber-optic LSPR platform have permitted the development of an immunosensor for the determination of a nonclinical application in plant viruses: Cymbidium mosaic virus (CymMV) and Odontoglossum ringspotvirus (ORSV) [ 67 ]. The limit of detection of viral antigens over antibody functionalized on gold nanorods was at picogram-per-liter levels (48–42).…”

The global burden of coronavirus disease 2019 (COVID-19) to public health and global economy has stressed the need for rapid and simple diagnostic methods. From this perspective, plasmonic-based biosensing can manage the threat of infectious diseases by providing timely virus monitoring. In recent years, many plasmonics’ platforms have embraced the challenge of offering on-site strategies to complement traditional diagnostic methods relying on the polymerase chain reaction (PCR) and enzyme-linked immunosorbent assays (ELISA). This review compiled recent progress on the development of novel plasmonic sensing schemes for the effective control of virus-related diseases. A special focus was set on the utilization of plasmonic nanostructures in combination with other detection formats involving colorimetric, fluorescence, luminescence, or Raman scattering enhancement. The quantification of different viruses (e.g., hepatitis virus, influenza virus, norovirus, dengue virus, Ebola virus, Zika virus) with particular attention to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was reviewed from the perspective of the biomarker and the biological receptor immobilized on the sensor chip. Technological limitations including selectivity, stability, and monitoring in biological matrices were also reviewed for different plasmonic-sensing approaches.

“… Malecka et al (2014) reported that the detection limit of PPV was 12.8 pg/ml, using an ion-channel genosensor labeled with Plum Pox Virus (PPV)-derived 22-mer and 42-mer complementary ssDNA. Lin et al (2014) reported that the detection time of a fiber optic particle plasmon resonance (FOPPR) immunosensor was within 10 minutes, and the detection limits of CymMV and ORSV were 48 pg/ml and 42 pg/ml, respectively, which is tens of times higher than the 1.2 ng/ml of ELISA. In addition, McClellan et al (2012) reported that the detection limit and the detection time of bean pod mottle virus (BPMV) using silicon photonic microring resonator (SPMR) were 10 ng/ml and 45 min, respectively, which is slightly higher and slightly shorter than that of ELISA.…”
