“…For example, a sensor was presented to monitor the freshness of fish by observing the color changes based on the pH level emitted [3]. On the other hand, toxins, such as Aflatoxins B1 or histamine in food, can be detected using multi-mode fiber and multi-core fiber [4] or surface plasmon resonance [5], [6] in optical sensors, respectively. Light indicating and optical sensors to detect toxic elements have great practical applications.…”

“…In [12], a chipless pH-sensor design was suggested to detect meat freshness based on changes in frequency using pH-sensitive material on the resonant structure. On the other hand, the work in [13] investigated the dips in reflection coefficient and its complex performance of the unique composition of oil over wide frequency bandwidth (3)(4)(5).…”

Chipless RFID sensor is currently one of the most promising sensor designs, especially in food safety sector, because it has a robust structure and is inexpensive for mass production. This paper proposes a simple, compact, and low-cost chipless RFID sensor tag for frozen food monitoring. The system consists of an interrogator antenna, which is an antipodal Vivaldi antenna, and a chipless RFID sensor tag inside a flat container that contains a small quantity of ice. When receiving power from the interrogator antenna, the sensor alters the frequency of the reflected signal if the ice melts. One of three states of the material in the container can be detected, i.e. ice, water, and air (empty container). The peak of the frequency response exhibits distinctively narrow 3-dB bandwidth of 35 -49 MHz, allowing multiple sensors to operate simultaneously within limited bandwidth and space; Peak center frequency is observed at 751 MHz or 838 MHz, for respectively ice and air, with no peak present for water. The system is simulated, analysed, and verified by measuring in free open space in a realistic environment. The measurement for ice melting over time is also measured and shown that frequencies of the peaks are slowly decreasing during the first 10 minutes after defrost and completely disappears after 15 minutes. The resonant peak reappears at 826 MHz after the tag is completely dry. A good tolerance to the background is also found when complex dielectric material is placed next to the sensor.

“…Plasmonic sensors generally offer fast on-site detection with compact setups and high sensitivity while giving the possibility of simultaneous data acquisition and multiplexing. These include surfaceenhanced Raman spectroscopy methods [17], [18], optical fiber-based surface plasmon resonance sensors [19]- [21], such as WaveFlex-biosensors [22], [23], and plasmonic sensors utilizing nanostructured sensor surfaces [24], [25]. Each of the systems mentioned above pose promising approaches for the fluid process monitoring.…”

Plasmonic sensors based on nanostructured metal substrates offer a promising solution for on-site implementation and continuous monitoring of process liquids due to their compact design, cost-effectiveness and rapid sensor response. The sensors are qualified for the functionalization with biological recognition elements and thus for biosensing. A functionalization with stimulusresponsive hydrogels further enhance their utility by enabling selective determination of specific substances in complex solutions. However, challenges arise in accurately interpreting the sensor signals due to the nonlinearity between the swelling curve of the hydrogel and the sensor signal and due to interferences from nontarget substances. An important objective of this study is to develop a methodology to accurately determine the concentration of a target substance in a multi-component solution, eliminating the influence of interfering substances. For this, it is imperative to enhance the comprehension of the system, elucidating the impact of the hydrogel's swelling state and of the composition on the sensor signal. An analytical model is presented, conveying a linear relationship between the sensor signal and the volume fraction of each constituent in the hydrogel. Based on the proposed model, a novel difference method is established to eliminate the influence of interfering substances, particularly at low concentrations of interfering substances. In a proof-of-concept, using an ethanol-sensitive hydrogel for detection of ethanol in aqueous ethanol-glucose solution, the method was validated, showing a negligible impact of the glucose concentration on the result.

The fiber surface plasmon resonance (SPR) sensor used for the detection of active ingredients in traditional Chinese medicine has the problems of low sensitivity and difficult specific recognition. This paper proposed a wave type fiber SPR sensor, which reduced the mode of transmitted light through a periodic wave structure and caused concentrated and total reflection of the transmitted beam at the interface between the bent peak cladding and the air. A 50 nm gold film was coated on the surface of the cladding in the wave structure area to form the SPR sensing area. By controlling the width and height of the wave structure to control the total reflection angle of the transmitted light, i.e., the SPR incidence angle, the sensitivity of the fiber SPR sensor was effectively improved to 4972 nm/RIU. Furthermore, HSP90AA protein was modified on the gold film of the sensor to achieve specific detection of hyperoside. The longest single detection time was only 3 minutes, and the detection sensitivity was 0.53 nm/(µg/ml), with a detection limit as low as 0.68µg/ml, which is comparable to liquid chromatography. The proposed wave type fiber SPR sensor is fast in production and has high structural mechanical strength, providing a new approach for the rapid, highly sensitive, and specific detection of active ingredients in traditional Chinese medicine.
