Correction to: Enhanced laser-induced PEDOT-based hydrogels for highly conductive bioelectronics

In the Fig. 1 of ‘Enhanced laser-induced PEDOT-based hydrogels for highly conductive bioelectronics’ (National Science Review, Volume 12, Issue 6, 2025, nwaf136, https://doi.org/10.1093/nsr/nwaf136), two errors were identified. In Fig. 1b, the X-axis label should be corrected from ‘Strain (%)’ to ‘Wavelength (nm)’. In Fig. 1e, the scale bar should be corrected from ‘10 μm’ to ‘10 mm’. Design and fabrication of highly conductive hydrogels. (a) Schematic of design principles of bioelectrodes via MLLC coupled with laser-induced phase separation for implantable nerve stimulation and signal recording. (b) Ultraviolet-visible absorption spectra of pure PEDOT:PSS, MLLC ink and MLLC ink optimized with ionic liquid (IL). (c) Electrical conductivity of PEDOT:PSS and MLLC films with and without laser processing (n = 5). (d) Calculated thermal distribution inside the PEDOT:PSS and MLLC films. (e) Photo of enhanced laser-induced PEDOT:PSS electrodes array patterned on a PET substrate. (f) Optical image, (g) corresponding height profile and (h) 3D topography of patterned ELIP bioelectrodes array with a width of ∼3 μm on the PET substrate. The corrected Fig. 1 is presented below. We sincerely apologize for any inconvenience caused. This correction does not affect the conclusions of the article.
