Corrigendum to “Rapid antibody-free fluorescence quenching-based protein detection using molecularly imprinted sensors”(Sensors and Actuators B: Chemical, (2026), 461, C, (139977), (S0925400526005551), 10.1016/j.snb.2026.139977)

The authors regret “that errors were present in the published version of the article. The following corrections should be noted: 1.Correction to authors address (a) Correction to authors address (a) The authors address ^a should read “Micro/Bio/Nanofluidics Unit” (instead of “Micro/Bo/Nanofluidics Unit”). 2.Correction to Section 3.2 (title and text): Correction to Section 3.2 (title and text): The section title should read “3.2. Microfluidic platforms” (instead of “3.2. Microfluidic platforms for shear flow”). The text of Section 3.2 should be replaced with the following: An optimised cross-slot rheometer (OSCER) device was produced using an ELEGOO Mars 5 Ultra. The OSCER is based on a planar cross-slot geometry with two incoming and outgoing flows placed orthogonal to each other, as described by Calabrese et al. [38]. The device has a height H = 0.3 mm and a channel width of W = 0.3 mm at the inlets and outlets, yielding an aspect ratio α = H/W = 1, generating an extensional-dominated flow field near the central stagnation point, where shear is minimised over a finite region. The flow inside the channels is generated by Nemesys low-pressure syringe pumps (Centoni, GmbH) and Hamilton Gastight syringes, which infuse the liquid at the inlet. The flows were equilibrated for at least 5 s before injection of the MIP microparticles and measurements and confirmed as being steady by inspection of the microparticle image. All measurements were performed at ambient temperature (25 ± 1 °C). 3.Correction to Sections 3.3 and 3.5: Correction to Sections 3.3 and 3.5: All concentration units reported as mg mL⁻¹ should be corrected to μg mL⁻¹. 4.Correction to Fig. 4 caption: Correction to Fig. 4 caption: “Fig. 4. (A) Schematic illustration of the optimised shape cross-slot extension rheometer (OSCER) device, adapted from Calabrese et al. [38], not to scale. (B) Photograph of OSCER 3D printed device assembled and mounted for flow experiments, (C) Optical microscopic image of the cross-slot junction region confirming uniform channel dimensions.” 5.Correction to Fig. 5 and Fig. 5 caption: Correction to Fig. 5 and Fig. 5 caption: An incorrect version of Fig. 5 was published. The correct version of Fig. 5 and its corresponding caption below replaces the original. 6.Correction to Fig. 6 caption: Correction to Fig. 6 caption: “Fig. 6. Calibration plot comparing the amount of protein loaded (nM) in human serum, with the fluorescence emission intensity (CPS).” 7.Correction to Table 3: Correction to Table 3: The final row in Table 3 should read: “23.5 → 23.2 (± 0.9) → 98.7 → 1.3”.” These corrections do not affect the scientific results or conclusions of the article.
