IL6 and Sepsis: The 150 nm sized SeNPs are proposed as the best all-aroundlabelfor the detection of IL-6, offering the lowest LOD of 0.1 ng/mL andcomparable visual detection to 40 nm AuNPs at high analyte concentrations.The lower LOD offered by 150 nm SeNPs over 40 nm AuNPs is especiallydesirable in applications where the early detection of an illnessis critical to the speed with which targeted treatment can be provided,e.g., the early detection and treatment of sepsis in primary caresettings.
