Emergency Treatment and Photoacoustic Assessment of Spinal Cord Injury Using Reversible Dual‐Signal Transform‐Based Selenium Antioxidant (Small 35/2023)

Spinal Cord Injuries In article number 2207888, Xianjin Du, Jian Zhang, Hongsheng Lin, Yuhui Liao, and co‐workers design an emergency treatment and photoacoustic severity assessment (ETPSA) strategy for spinal cord injury (SCI) based on the selenium (Se) matrix antioxidant system Se@BDP‐DOH nanoparticles, which can real‐time evaluate the severity of SCI using photoacoustic signals and simultaneously effectively inhibit oxidative stress‐induced damage in neuron cells to reconstruct the redox microenvironment, accompanying the increasing branch and extension of nerves.
