Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Ultrasensitive MicroRNA Detection Combining Reduced Graphene Oxide Electrolyte‐Gated Transistors and Machine Learning

Small, EarlyView.
We developed an ultrasensitive and highly selective biosensor by integrating bio‐functionalized reduced graphene oxide (rGO) electrolyte‐gated transistors (EGTs) and machine learning (ML) to detect miRNAs (miR‐34a, miR‐34b, and miR‐34c) associated with cancer and neurological disorders.

A multifunctional near‐infrared dual‐channel off‐on‐off probe for sequential detection of fluoride and hypochlorous acid: Multimatrix applications

Smart Molecules, EarlyView.
This multifunctional, sequence‐specific probe (DHM) enables stepwise detection: fluoride triggers red/near‐infrared emission via cleavage, then hypochlorous acid induces blue fluorescence. It achieves fast, selective visual detection in environmental samples, foods, and in vivo models.
