Bioactive materials are a special class of biomaterials that can react in vivo to induce biological response or regulate functions, thus achieving better curative effect than traditional inert biomaterials. For cancer theranostics, compared with organic polymer nanomaterials, inorganic nanomaterials possess unique physical and chemical properties, have stronger mechanical stability on the basis maintaining certain bioactivity, easy be compounded various carriers (polymer carriers, etc.), so as achieve specific antitumor efficacy. After entering nanoscale, due nano-size effect, high surface area nanostructures, exhibit effects, which significantly influence interaction organisms.

In recent years, the CRISPR/Cas12a-based sensing strategy has shown significant potential for specific target detection due to its rapid and sensitive characteristics. However, "always active" biosensors are often insufficient manipulate nucleic acid with high spatiotemporal control. It remains crucial develop devices that can be activated at desired time space by a remotely applied stimulus. Here, we integrated photoactivation CRISPR/Cas12a system DNA RNA detection, aiming provide control sensing. By rationally designing recognition sequence, this could recognize HPV16 survivin, respectively. We combined lateral flow assay strip test realize visualization of cleavage signals, displaying instant application capabilities. Additionally, also successfully realized temporary fluorescent activity survivin in vivo, allowing acids avoiding risk contamination from premature leaks during storage. Our suggests platform triggered sense various targets, expanding technical toolbox precise biological medical analysis. This study represents advancement applications disease diagnosis treatment.

Detection and imaging of dual miRNAs based on AND logic gates can improve the accuracy early diagnosis disease. However, a single target may lead to false positive. Hence, this work rationally integrates hyperbranched rolling circle amplification (HRCA) with Cas12a by replacing PAM sequence bubble sensitively detect image miRNA-10b miRNA-21 gate.

Abstract Synthetic biochemical circuits (e.g., DNA circuits) remain at the forefront of intracellular biosensing tasks yet are hindered by undesired off‐site activation and accompanying signal leakage. Herein, study attempts to overcome this limitation developing a simple‐yet‐powerful endogenous glutathione (GSH)‐regulating tactic that permits robust distinguishable on‐site microRNA (miRNA) imaging under disturbed redox homeostasis. Specifically, hierarchically activated catalytic (HAD) circuit is fabricated grafting disulfide linkage within entropy‐driven circuitry (EDC) reactants. It exemplified HAD system promises spatiotemporally selective microRNA‐21 (miR‐21) in living cells differentiation tumor from normal cells. The correlationship between GSH miRNA extensively explored live cells, can substantially expand toolbox for profiling processes.
