This paper presents a highly sensitive flexural plate-wave (FPW)-based microsystem for rapid detection of tetrahydrocannabinol (THC) in human urine. First, a circular-type interdigital transducer (IDT) was integrated with a circular-type silicon-grooved reflective grating structure (RGS) to reduce insertion loss. Then, with lower insertion loss (-38.758 dB), the FPW device was used to develop a novel THC biosensor, and the results reveal that this FPW-THC biosensor has low detection limit (1.5625 ng/mL) and high mass-sensitivity (126.67 cm²/g). Finally, this biosensor was integrated with field-programmable gate array (FPGA) board and discrete components for prototyping a FPW readout system, whose maximum error was 12.378 kHz to ensure that the linearity of detection up to R-square is equal to 0.9992.

Background: Hypochlorous acid (HClO) is a crucial disinfectant in the food industry. It can be used to soak perishable foods like vegetables, fruits, eggs, fish, and raw meat before processing and storage, eliminating microorganisms, bacteria, fungi, and pathogens to ensure food safety. HClO also helps preserve vegetables and fruits by reducing ethylene production, delaying rotting, decreasing cell membrane permeability, inhibiting polyphenol oxidase activity, and postponing discoloration.

Objectives: Authentic patient and family engagement in child health research is defined as researchers working in partnership with patients and families on all aspects of the research process, including refining the research question, tailoring the intervention, devising study procedures and disseminating study findings. While there is good evidence of a positive impact of patient engagement on the research process, on research teams and on patient partners, there are few empirical data on the impact of patient and family engagement on research quality and dissemination. We conducted a systematic review to compare research quality and dissemination metrics for paediatric randomised controlled trials (RCTs) that engaged patients and families in the research process with trials that did not.
