teract for 1700 s. The TLR1 Purity & Documentation surface was DTT resolution (1 mg/mL) was injected and permitted to interact for 1700 s. The surface was subsequently washed utilizing PBS buffer till the baseline was obtained. An SPR signal subsequently washed employing PBS buffer till the baseline was obtained. An SPR signal jump of 311 m from the initial baseline was observed with a rise in surface density jump of 311 mfrom the initial baseline was observed with a rise in surface density 2 to two.54 ng/mm2 , as determined from Equation (two). to 2.54 ng/mm , as determined from Equation (2). Surface density = Response (m )/conversion aspect [m mm2 /ng)] Surface density = Response (m/conversion aspect [m(mm2/ng)] (2) (2)The DTT-modified AuNPs/Au electrode surface was introduced with ACR (1 ), at a potential of +0.9 V, which enhanced the SPR signal. Following the potential drop, the baseline stabilized at 1173 m , indicating plausible polymerization of ACR and its interaction with DTT. This was followed by washing to eliminate any unbound ACR molecules, top to a reduce in the SPR signal to 1046 m . The surface density calculated immediately after the deposition was 8.57 ng/mm2 . It need to be noted that with no the applied possible, the addition of ACR provoked no SPR response.Nanomaterials 2021, 11, 11, 2610 Nanomaterials 2021, x FOR PEER REVIEW11 of 16 16 11 of. Figure 6.
