Chronic, non‐healing wounds pose significant challenges for public health, particularly in the context of diabetes, and carry significant economic consequences. This article introduces a new solution in the form of a wireless theranostic patch, developed to meet the critical need for real‐time monitoring and targeted treatments to facilitate optimal healing. The patch incorporates advanced materials that are both multifunctional and electro‐responsive, leveraging a sophisticated blend of smart hydrogels and wearable bioelectronics to support diabetic wound management with unparalleled efficacy. With electro‐responsive multifunctional polymer hydrogels at its core, the patch delivers a stretchable, antimicrobial, and moist environment for the wound, with added benefits such as conductivity and visibility. The materials also allow for continuous and autonomous monitoring of glucose and pH levels, providing precise and personalized treatments like insulin delivery via iontophoresis and electrical stimulation. Animal models have demonstrated that this integrated system is highly adaptable, effectively promoting wound closure and healing. Overall, the wireless theranostic system offers an exciting prospect for personalized healthcare solutions, adopting a patient‐centric approach that prioritizes real‐time, targeted care for chronic wounds. Its incorporation of advanced materials and electro‐controlled treatments paves the way for new and innovative approaches to wound management. [ABSTRACT FROM AUTHOR]

High-quality violet-blue emitting Zn xCd1- xS/ZnS core/shell quantum dots (QDs) are synthesized by a new method, called 'nucleation at low temperature/shell growth at high temperature'. The resulting nearly monodisperse Zn xCd1- xS/ZnS core/shell QDs have high PL quantum yield (near to 100%), high color purity (FWHM) <25 nm), good color tunability in the violet-blue optical window from 400 to 470 nm, and good chemical/photochemical stability. More importantly, the new well-established protocols are easy to apply to large-scale synthesis; around 37 g Zn xCd1- xS/ZnS core/shell QDs can be easily synthesized in one batch reaction. Highly efficient deep-blue quantum dot-based light-emitting diodes (QD-LEDs) are demonstrated by employing the Zn xCd1- xS/ZnS core/shell QDs as emitters. The bright and efficient QD-LEDs show a maximum luminance up to 4100 cd m−2, and peak external quantum efficiency (EQE) of 3.8%, corresponding to 1.13 cd A−1 in luminous efficiency. Such high value of the peak EQE can be comparable with OLED technology. These results signify a remarkable progress, not only in the synthesis of high-quality QDs but also in QD-LEDs that offer a practicle platform for the realization of QD-based violet-blue display and lighting.
