Bioinspired Synthesis of All‐in‐One Organic–Inorganic Hybrid Nanoflowers Combined with a Handheld pH Meter for On‐Site Detection of Food Pathogen

With a mild elaborately bioinspired one-pot process, Con A-GOx-CaHPO4 nanoflowers are prepared. Employing the as-prepared all-in-one hybrid nanoflowers as signal tags, a simple but potentially powerful amplification biosensing technology for the detection of food pathogen with excellent simplicity, portability, sensitivity, and adaptability is achieved.
