Multiple Defect‐Induced High‐Resolution Near‐Infrared Mechanoluminescent Materials for Non‐Destructive Detection of Blood Glucose and Lipids

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(50)

Published: Nov. 6, 2024

Mechanoluminescence (ML) materials, known for their ability to convert mechanical energy into light, are increasingly recognized potential applications, such as in intelligent stress sensing, vivo bioimaging, and non-destructive monitoring. However, the low signal-to-noise ratio (SNR) narrow-band emission of single-defect-induced ML materials usually limit biological-related practical applications. Here, these limitations will be addressed by modulating microstructure evolution Y
