“…To meet high-throughput requirements of a clinical diagnostic tool, we have shown that automated sample preparation can increase technical replicate consistency and conformity, maximising the number of samples probed in the sampling area. In terms of data processing and accessibility, spectral apps are also currently in development that would allow mobile devices to access and manipulate spectra for real-time reporting 17 .…”

Accurate early diagnosis is critical to patient survival, management and quality of life. Biofluids are key to early diagnosis due to their ease of collection and intimate involvement in human function. Large-scale mid-IR imaging of dried fluid deposits offers a high-throughput molecular analysis paradigm for the biomedical laboratory. The exciting advent of tuneable quantum cascade lasers allows for the collection of discrete frequency infrared data enabling clinically relevant timescales. By scanning targeted frequencies spectral quality, reproducibility and diagnostic potential can be maintained while significantly reducing acquisition time and processing requirements, sampling 16 serum spots with 0.6, 5.1 and 15% relative standard deviation (RSD) for 199, 14 and 9 discrete frequencies respectively. We use this reproducible methodology to show proof of concept rapid diagnostics; 40 unique dried liquid biopsies from brain, breast, lung and skin cancer patients were classified in 2.4 cumulative seconds against 10 non-cancer controls with accuracies of up to 90%.

“…In addition, development of sensors and devices with wireless access (wi‐fi or bluetooth), applications for access and remote analysis of spectral data (Evans, Clemens, Casey, & Baker, ), and even images should be available in the coming years and should be incorporated into portable devices (Ellis, Muhamadali, Haughey, Elliott, & Goodacre, ), being easier to manage and expanding its use to the final consumer. The connection of the portable device to the network would allow quick responses to be used in real time or for predictions, becoming part of the “Internet of things.” The “Internet of Things” has been recognized as a powerful tool to realize new levels of control, allowing, for example, to improve the monitoring and traceability of food through remote control (Sundmaeker, Verdouw, Wolfert, & Pérez Freire, ).…”

Food fraud in herbs and spices is an important topic, which has led to new technologies being studied as potential tools for fraud identification. Nontargeted technologies have proven to be a useful tool for the authentication of herbs and spices. The present review focuses on the use of near‐infrared, hyperspectral imaging, Fourier‐transform infrared, Raman, nuclear magnetic resonance, and electron spin resonance spectroscopy for the authentication of spices, which includes the determination of origin and irradiated spices and the identification of adulterants. The methods developed based on vibrational spectroscopy combined with chemometric techniques seem to be promising tools for determining the presence of adulterants and contaminants in herbs and spices. On the other hand, nuclear magnetic resonance seems to be the most efficient technology to determine the origin of herbs and spices although, for some cases, studies with near‐infrared spectroscopy can be a viable substitute. Electron spin resonance spectroscopy is the technique par excellence used for the authentication of irradiated herbs and spices, so its use should be expanded to many more spices’ varieties. Portable devices are preferred by those involved in the food industry, due to its manageability and low cost. Data fusion and big data are shown as promising tools for spice fraud control. In conclusion, spectroscopic techniques show a great efficiency to authenticate spices, although their evaluation must be expanded to other spice varieties, to new strategies of data analysis (as data fusion and big data), and to the use of portable devices.

“…With further innovation and future developments in sensor technologies and computing, such as wired or wireless connectivity (i.e. Wi-Fi, Bluetooth) and/or remote access capability 116 built into the portable and handheld devices discussed here, these rapid methods could be networked and thus used to detect trends in the food market (perhaps even before any food security threat/event is acknowledged by regulators) and thus could very easily sit within the umbrella of the Internet of Things (IoT). Which, like cloud computing, will not be one but rather a series of paradigms and platforms which are set to explode and impact on all our lives within the next decade.…”
