Self-healing technology promises a generation of innovation in cross-cutting subjects ranging from electronic skins, to wearable electronics, to point-of-care biomedical sensing modules. Recently, scientists have successfully pulled off significant advances in self-healing components including sensors, energy devices, transistors, and even integrated circuits. Lasers, one of the most important light sources, integrated with autonomous self-healability should be endowed with more functionalities and opportunities; however, the study of self-healing lasers is absent in all published reports. Here, the soft and self-healable random laser (SSRL) is presented. The SSRL can not only endure extreme external strain but also withstand several cutting/healing test cycles. Particularly, the damaged SSRL enables its functionality to be restored within just few minutes without the need of additional energy, chemical/electrical agents, or other healing stimuli, truly exhibiting a supple yet robust laser prototype. It is believed that SSRL can serve as a vital building block for next-generation laser technology as well as follow-on self-healing optoelectronics.

We developed a microfluidic microwell device integrating SERS substrate for an efficient bacteria encapsulation and enrichment followed by in situ SERS-AST measurement, which can potentially apply for high throughput and multi-parallel AST.

Additive manufacturing allows 3D items to be fabricated in a "bottom-up" fashion without subtraction (e.g., cutting and shearing) and formation (e.g., assembling and molding), leading to one-step production, maximum material utilization, and minimum expense, in stark contrast to traditional methods. Direct printing by computeraided design [1,2] boosts mass customization and lessens operation errors; even a layman can formulate any desired products free from geometrical constraints, constitutional restraints, and skill limitations. Inspired by the idea of online-distributed blueprints and localized production, the public can download digital prototypes from the cloud, modify models to fit their needs, and construct real devices anywhere, promising a world where
