“…This is because upon evaporation the water first depletes the micron-scale inter-fiber pores, which determine the optical appearance of paper. 6 Most of the water in the fibers is still present and only after it has evaporated as well does e CD (t) reach a steady state. For pure water, 80-90% of the maximum hydroexpansion amplitude disappears after evaporation is complete.…”

“…Samples in which the co-solvent is intended to partially remain within the inter-fiber pores were created with a high concentration of 60 wt%. Samples in which a pore-fiber equilibrium is required were prepared with low concentration solutions of 30 wt% and underwent a post-deposition rehydration treatment with water, 6 since water accelerates the pore-fiber equilibration. The desired co-solvent content θ cs was achieved by deposition of aqueous co-solvent solution droplets of different volumes.…”

“…For a given non-equilibrium data set y cs,neq , (I/I 0 ) neq , and e neq , a fraction of the co-solvent is in the intra-fiber pores while another fraction is in the inter-fiber pores. Therefore, y cs,fibers can be obtained by inverting eqn (6), which describes the strain corresponding to a certain intra-fiber content, y cs,fibers = e neq /0.0347.…”

Electrochemical biosensing represents a highly effective technology for detecting disease biomarkers given its high sensitivity, low and clinically relevant limit of detection, and cost effectiveness. However, in complex media such as urine, blood, sweat or saliva, biosensing performance can be significantly impacted by electrode biofouling by proteins, cells, lipids, and other matrix components. Such biofouling leads to reduced signal from the target analyte coupled with an elevated background signal, resulting in poor signal‐to‐noise ratios (SNRs), reduced sensitivity, and lower specificity. This comprehensive review describes the design of anti‐fouling polymers and peptides as a potential solution to prevent or suppress electrochemical biosensor fouling. Various anti‐fouling polymers and peptides developed for improved biosensing in complex media are summarized in the context of their mechanism(s) of anti‐fouling, methods of deposition, and practical applications. Recent advances and persistent challenges in the field are also reviewed to provide perspectives on new directions toward enhancing anti‐fouling in electrochemical biosensors.
