“…A successful and rapid detection of E. coli in fruit juice using a portable NF-LAPS device was reported (Table 3). By taking advantage of their large surface area and high porosity, electrospun nanofibers enable high loading of biomolecules and efficient interaction with the analyte, as well as enhancing analyte diffusion, thus increasing biosensor sensitivity (Altan & Yılmaz, 2021).…”

“…In the last years, electrospun nanofibers have developed as a possible approach to improve the performance of biosensors. These nanofibers present a porous structure, adjustable surface functionality, low barrier to diffusion, and high surface‐to‐volume ratio (Altan & Yılmaz, 2021). Electrospinning technique has developed since its first production time, and it has been used to be a technique to fabricate functional nanofibers.…”

Foodborne diseases caused by pathogen bacteria are a serious problem toward the safety of human life in a worldwide. Conventional methods for pathogen bacteria detection have several handicaps, including trained personnel requirement, low sensitivity, laborious enrichment steps, low selectivity, and long‐term experiments. There is a need for precise and rapid identification and detection of foodborne pathogens. Biosensors are a remarkable alternative for the detection of foodborne bacteria compared to conventional methods. In recent years, there are different strategies for the designing of specific and sensitive biosensors. Researchers activated to develop enhanced biosensors with different transducer and recognition elements. Thus, the aim of this study was to provide a topical and detailed review on aptamer, nanofiber, and metal organic framework–based biosensors for the detection of food pathogens. First, the conventional methods, type of biosensors, common transducer, and recognition element were systematically explained. Then, novel signal amplification materials and nanomaterials were introduced. Last, current shortcomings were emphasized, and future alternatives were discussed.

Zeolitik imidazolat kafes yapıları (ZIF'ler), geniş yüzey alanı, yüksek gözeneklilik, olağanüstü termal ve kimyasal kararlılık gibi ayırt edici özelliklerinden dolayı büyük ilgi görmektedir. ZIF'lerin yüzey alanını etkileyen morfolojik özelliklerini kontrol edebilmek için sentezlenen yapıların oluşumunda önemli rol oynayan sentez parametrelerinin etkisinin bilinmesi gerekmektedir. Bu çalışmanın amacı, gıda alanında uygulama potansiyalinin geliştirilmesi için ZIF-67 yapılarının farklı koşullar altında sentezlenmesidir. Sentezlenen malzemelerin morfolojileri (FE-SEM, polarize ışık mikroskobu), yüzey alanları (BET), kimyasal yapıları (FTIR) ve kristallikleri (XRD) incelenmiştir. Sentez esnasında TEA kullanılması ve kobalt nitrat ile 2-mIM konsantrasyonun artırılması dodekahedron yapının bozulmasına sebep olmuştur. Metanol miktarı azaltıldığında ise ZIF-67 nanoparçacıklarının boyutlarının arttığı belirlenmiştir. Dodekahedron morfolojiye sahip ZIF-67 nispeten yüksek bir nitrojen sorpsiyonu ve BET yüzey alanı göstermekle birlikte, karakteristik C-H ve C=N germe zirvelerine de sahiptir. Elde edilen ZIF-67 yüklü nanoliflerin; gıda kirleticilerinin adsorpsiyonu, gıda paketleme sistemlerinin geliştirilmesi, gaz depolama ve biyosensörler gibi gıda uygulamaları için umut verici olduğu düşünülmektedir.
