Correction to: NPG Asia Materials https://doi.org/10.1038/s41427-022-00401-8, published online 24 June 2022
This article contains errors in Figure 5a. The fluorescence image of hybrid hydrogel microparticles of Figure 5a (v) was wrongly given due to the mistaken image inserted during the assembly of Figure 5. These errors don’t affect the results or conclusions of this article. The authors apologize for any confusion. The correct Figure 5 is reproduced below.
Figure 5. Fluorescent intensities and reflection curves of the hybrid PEGDA-CDs@Cu/Alg microparticles with different PPi concentrations. a Fluorescent images of hybrid hydrogel microparticles in response to different concentrations of PPi. From i to vi: 0, 1, 2, 4, 6, and 8 mM, respectively. b Fluorescent spectra of the microparticles after treating with different PPi concentrations of 0, 1, 2, 4, 6, 8, 9, and 10 mM. Inset shows the plot of fluorescent intensity at 535 nm according to PPi concentration. c Reflection spectra of the microparticles with an initial reflection peak value at 589 nm after treating with different PPi concentrations of 0, 1, 2, 4, 8, and 10 mM. The scale bar in (a) is 200 µm.
