High Sensitivity Cardiac Troponin I Detection via MP‐Locked Aptamer and Multimeric DNAzyme‐Coupled Hyperbranched Hybridization Chain Reaction

open access: yesSmall, EarlyView.
We report a magnetic particle anchored locked aptamer platform integrated with hyperbranched HCR and DNAzyme amplification for enzyme‐free, ultrasensitive detection of cardiac troponin I. The assay achieves a 0.25 ng/L detection limit within 25 minutes and enables cross‐species MI detection, with machine learning classification reaching 90% accuracy ...

Selective Lipoprotein Removal Enables High‐Purity EV Isolation from Plasma via Aptamer‐Based Mesh Filtration

open access: yesSmall, EarlyView.
A novel affinity‐based mesh filtration system, ApoFilter, enables selective removal of plasma lipoproteins via sequential aptamer‐functionalized layers targeting ApoA1 and ApoB100. While EVs pass through unimpeded, (V)LDL and HDL are rapidly depleted.

Motorized DNAzymes Drive Enhanced Electrochemical Biosensing for Rapid Bacterial Detection

open access: yesSmall Methods, EarlyView.
The micromotor DNAzyme analyzer (Motolyzer) enables sensitive electrochemical detection of Legionella pneumophila proteins in unprocessed samples with high specificity. Upon target recognition, DNAzymes actively release redox barcodes, which are detected on DNA‐functionalized electrodes.

Advances in cholesterol and lipoproteins detection for healthcare: A review

open access: yesVIEW, EarlyView.
Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most
