This study introduces a one-pot isothermal amplification assay for ultrasensitive analysis of terminal deoxynucleotidyl transferase (TdT) activity. The system realizes recycled activation of CRISPR/Cas12a, enabling exceptional signal amplification. This approach maximizes the simplicity of the detection method, offering a promising avenue for molecular disease diagnosis.

A series of polyurethanes (PU-GT) were prepared using polyglycolide-block-polytetrahydrofuran-block-polyglycolide (PGA-PTHF-PGA), polytetrahydrofuran homopolymer (PTHF), glycerol, and hexamethylene diisocyanate (HDI) by a one-pot synthesis method. The non-isothermal crystallization and subsequent heating curves showed that the PTHF component in these polyurethanes could crystallize in a temperature range of -11.5~2.

The detection of heavy metal ions, particularly lead (Pb²⁺), in environmental samples is crucial for public health and safety. Current nucleic acid signal amplification methods for Pb²⁺ detection often rely on biological enzymes and are limited in applicability due to high costs, prolonged detection times, and nonspecific adsorption. In this study, we introduce an enzyme-free, DNAzyme-mediated isothermal catalytic hairpin assembly (DMICHA) assay, which combines a DNAzyme-based Pb²⁺ recognition module with a signal amplification process utilizing isothermal catalytic hairpin assembly (CHA).

MicroRNA (miRNA) is a promising biomarker for the early diagnosis of pancreatic cancer. To enable sensitive and reliable miRNA detection, we have developed a one-pot isothermal CRISPR/Dx detection system by combining rolling circle amplification (RCA) and CRISPR/Cas12a. RCA and CRISPR/Cas12a reactions are carried out in a single closed tube, bypassing the transferring step.
