Rapid wound dressing and effective antibacterial therapy are of extreme importance for skin wounds treatment in emergency . By combing the advantages of in situ electrospinning and AIE PSs, Zhao et al. developed a feasible and rapid strategy for wound infection treatment of surgery or accident injuries by in situ depositing AIEgen based nanofibrous dressing (Fig. ) . In their approach, AIEgens (TBP)-incorporated poly(ε-caprolactone) (PCL) solution could be readily electrospun by a handheld electrospinning device to form the nanofibrous dressing, which was closely and well adhesive to the wound surface. In vitro (Fig. ) and in vivo (Fig. ) experiments demonstrated that the AIE nanofibrous dressing exhibited excellent antibacterial activities and greatly promoted the wound healing process. Thus, the strategy of in situ deposition of AIE nanofibrous dressing via handheld electrospinning device can provide personalized therapies for emergency wounds with the advantages of convenience, versatility and universality.
