A comparison of biosensing techniques for protein sensing. SPR = Surface Plasmon Resonance; SMR = Suspended Microchannel Resonators; NW = Nanowires; LFA = Lateral Flow Assay; MRR = Microring Resonator; QCM = Quartz Crystal Microbalance; BBA = BioBarcode Assay; IFA = Immunofluorescence Assay; MC = Microcantilever; H-MS = Hybrid-Microsphere [18]; FL = FLOWER. The dashed line represents the present state of the art, not including recent advances in WGM sensing. For cases where the limit of detection is determined by analyte mass, a molecular weight of 34 kDa is assumed (Partially adapted from [11]).
