Cross linker

CagA antigen and antibodies were procured from the Max von Pettenkofer Institute of Hygiene and Medical Microbiology, Ludwig Maximilian University, Munich, Germany and stored at −20 °C till further use. The monomer, cross-linker, initiator, and methanol were purchased from Sigma-Aldrich, India, and were used without any further purification. Other chemicals, including K₃[Fe(CN)₆], K₄[Fe(CN)₆], and KCl, were purchased from Sisco Research Laboratory (SRL), Mumbai, India. All other chemicals were of analytical reagent (AR) grade and all aqueous solutions were prepared in double distilled water throughout the experiments. Cyclic voltammetric (CV) and electrochemical impedance studies (EIS) were performed using Bio-Logic Science Instruments SP-200 with EC-Lab^® software with an impedance analysis module. The working electrode was the screen-printed carbon electrode (SPE). Scanning electron microscopy (SEM) and Brunauer–Emmett–Teller (BET) were used to study the surface morphology and surface area of synthesized MIP with and without template CagA. The Material Studio version 2018r1 software package (Accelrys Inc., San Diego, CA, USA) [28 ] was used to conduct computational simulations.

Self-healing
cross-linked gel electrolytes
based on PEGDA were obtained through in situ UV polymerization
of precursor solutions. All the procedures described in the following
were performed in an argon-filled glovebox (MBraun, O₂,
H₂O < 0.5 ppm). PEGDA, cross linker, photo initiator,
and the azo dye were all purchased from Sigma-Aldrich; the liquid
electrolyte, LP30 (LiPF₆ 1 M in EC/DMC 50/50 v/v), was
provided by Solvionic. The UPyPEG₃₅₀₀₀UPy self-healing
unit was synthesized as described in detail in ref (17 (link)). The UPy-acrylate monomer
(UPy-MA, a comonomer shown in Figure S1) was synthesized as described in the following section.
