Fig. 4From: Longitudinal Zeolite-Iron Oxide Nanocomposite Deposited Capacitance Biosensor for Interleukin-3 in Sepsis DetectionDetermination of IL-3 on the anti-IL-3-modified surface. a Identification of 100 pg/mL of IL-3. Clear changes in capacitance were noted after dropwise addition of IL-3. The figure inset displays the schematic. b Titration of different IL-3 concentrations onto anti-IL-3 antibody. With all concentrations of IL-3, capacitance changes were notedBack to article page
