Near‐infrared light‐activated aptamer‐based nanoprobe for spatiotemporally resolved detection of L‐lactate in colorectal cancer

BMEMat, EarlyView.
A near‐infrared (NIR) light‐activated “lock‐key” nanodevice is reported for spatiotemporally resolved detection of intratumoral L‐lactate. The system stays silent until deep‐penetrating NIR light remotely unlocks its function, allowing for precise sensing within tumors.

CO2‐Driven Synthesis of Holey Edge‐Carboxylated Graphene for Tunable Electronic Interactions in Cu–CeO2‐Catalyzed Water‐Gas Shift Reaction

Carbon Energy, EarlyView.
Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.
