In this review, advances regarding stabilisation and production of nanosuspensions are briefly covered. Updates on the methods used to convert nanosuspensions to solid oral dosage forms (e.g., powder, granules, pellets, tablets, and films) are presented in depth. From these methods, spray drying and freeze drying are widely used. Granulation and hot-melt extrusion allow straightforward downstream processing, while printing exhibits the potential for dose personalisation.

Rapid screening is an effective way for food safety control, which highly relies on the development of sensitive, specific, and convenient detection methods. The multicolor colorimetric biosensors based on gold nanomaterials have evolved into advanced tools for detecting various hazards in food, with intuitive readout. The excellent localized surface plasmon resonance (LSPR) properties of gold nanomaterials enable them to exhibit bright colors when used as chromophores. In addition, the small changes in the morphology of gold nanomaterials can lead to significant changes in the wavelength of the LSPR peak, resulting in vivid color changes. Since the color discrimination ability of the normal human eye is usually superior to the intensity change ability, the way in which different concentrations of targets represent vivid color changes makes it feasible to fabricate sensors with improved accuracy in visual semi-quantitative detection. By combining with various signal amplification strategies, the detection sensitivity of the constructed sensors can be further improved, even reaching the level of pg/mL. In this review, two strategies for changing the morphology of gold nanomaterials in constructing multicolor colorimetric biosensors, namely the etching strategy and the growth strategy were discussed. We also highlight current progress in developing different gold nanomaterial-based multicolor colorimetric biosensors for detecting various hazards in food. The hazards in food samples are classified as pathogens, mycotoxins, indicators of food freshness, pesticides, antibiotics, heavy metal ions, food additives, and hazards from food processing and packaging. The multicolor colorimetric biosensors based on gold nanomaterials represent a promising tool for visual detection of hazardous materials in food.</p>","PeriodicalId":358,"journal":{"name":"Journal of Food and Drug Analysis","volume":"32 3","pages":"274-295"},"PeriodicalIF":2.6,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11464037/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142783768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both CD types maintain approximately 80% of their fluorescence intensity after 120 min of continuous 365 nm UV exposure, underscoring their stability and suitability for prolonged biological studies. Moreover, antioxidant activity tests showed that CDs-2 have a higher scavenging capacity, with an SC-50 value of 21.7 μg/mL, compared to 35.9 μg/mL for CDs-1, attributed to their higher content of surface functional groups during the extraction procedure. Notably, the results indicated that the carbonization process of fructus gardeniae leads to the formation of CDs, suggesting a potential link between traditional herbal treatments and modern nanotechnology.

To diagnose and treat AD promptly, it is essential to accurately measure the concentration of biomarkers in the cerebrospinal fluid or blood. However, due to the low concentrations of these biomarkers in the body, highly sensitive analytical techniques are required.
