Herein, we prepared curcumin (CUR) coated electrospun regenerated cellulose nanofiber (RCA) composites (CUR-Cot), to monitor the real-time spoilage of raw chicken. The physicochemical properties of the CUR-Cot sensor were completely studied. The surface modification, morphology, crystalline nature, and thermal stability of CUR-Cot were investigated by using various spectral, analytical, and microscopic techniques. Based on the results, the successful coating of CUR on the surface of RCA was confirmed. Interestingly, the CUR-Cot showed a significant change in total color difference value (ΔE, 0 days − 0.0–14.93, after 1 day – 14.93–23.64, after 2 days – 23.64–44.78, after 3 days- 44.78–55.22, and after 4 days – 55.22–60.96, detectable by the naked eye) in the real-time monitoring for chicken freshness. In addition, the present CUR-Cot smart colorimetric sensor is reversible with change in pH, and the reversed sensor can be reused. Furthermore, the hydrophobic nature of the CUR-Cot was confirmed by water contact angle analysis (WCA, contact angle of 90 ± 3.00), which increases its application and adaptability. Good antibacterial, barrier, and optical properties of the present CUR-Cot were also found. Overall, the results confirm that the usage of CUR-Cot sensor can be highly efficient, user-friendly, and non-destructive for the real-time monitoring of chicken freshness.</p></div>","PeriodicalId":52676,"journal":{"name":"Current Research in Biotechnology","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590262824000182/pdfft?md5=273c453ff8f94e676def0bd2a303fe31&pid=1-s2.0-S2590262824000182-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140042235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we systematically compared our protocols (with the suffix “-Si”) for preparing calcium oxalate (CaOx) monohydrate (COM), CaOx dihydrate (COD), magnesium ammonium phosphate (struvite), uric acid (UA), calcium phosphate dihydrate (brushite), hydroxyapatite (HAP), and calcium carbonate (CaCO₃) crystals with other protocols published previously. The morphological evaluation revealed that our protocols provided the most homogeneous and most typical monoclinic prismatic, bipyramidal, coffin lid and rectangle shapes of COM, COD, struvite and UA crystals, respectively. There were comparable morphological results for brushite, HAP and CaCO₃ crystals generated by different protocols. Our protocols provided the greatest yield for generating brushite crystals but with lower yields for others. Chemical analysis by Fourier transform infrared (FTIR) spectroscopy revealed comparable results among different protocols to generate each crystal type. In summary, all these protocols can be used to generate each crystal type.

The Light Emitting Diode (LED) lights are extensively utilized in the cultivation of several plant species, especially horticultural plants due to their lower power consumption and higher luminous efficiency compared to the conventional fluorescent lights. The aim of this review paper is to examine the potential of LED technology as it relates to plant lighting in greenhouses and other horticultural environments. It also desires to give an in-depth study of the advantages of LED lighting on plant development, yield, the production of secondary metabolites, and defense mechanisms. Horticultural lighting might undergo a revolution because LEDs are used in solid-state lighting, which would be a tremendous advancement after decades of research. LEDs may be used in a variety of horticulture lighting applications, such as tissue culture lighting, controlled environment research lighting, supplementary lighting, and photoperiod lighting for greenhouses. The primary impacts of light colors on plant performance are shown by the spectrum effects of LEDs as an independent source of light, together with the diverse sensitivity of many plant species and alternatives. LED light influences performance of enzyme, gene expression, cell wall formation, plant defense and postharvest quality. The spectrum reactions are mediated by the ambient lighting in a greenhouse, which also indicates a strong relationship between the additional supplementary lighting and changing environmental factors.
