제목 Multiplexed and time resolved immuno-biosensing of histamine by dual layer self-assembled liposomal nano-fluorophores
초록 Histamine as neurotransmitter, plays an important role in regulating the biological circadian rhythm and wakefulness in human health. Liposome-based multiplexed dual-layered assembled lipo-immuno-nanofluorophore biosensing was developed as a suitable biosensor device, which integrates immuno-liposomes in dual layered sandwich immunoassay format. Method 1 based on a dual-layered single wash procedure, which had a detection limit of 10 ppb and Method 2 was based on a dual layered one-by-one wash procedure and had a detection limit of 2–3 ppb that required 2 h 30 min to perform. Method 2 was chosen for further validation. The feasibility of developed multiplexed sensing was tested in histamine contaminated fresh mackerel fish, and canned fish (tuna), which showed a similar detection range but with low amplified fluorescence signal intensities and sufficient levels of histamine recovery from fresh mackerel (73.5-99.98%), canned tuna (79.08–103.74%).
