Summary: Here, a poly-adenine (polyA)-mediated programmable FRET-nanoflare is presented for ratiometric intracellular ATP imaging with anti-interference capability. The programmable polyA attachment enhances the signal response for ATP, and the FRET-based nanoflare avoids false-positive signals due to probe degradation in complex environments, showing great potential for clinical diagnosis.

Summary: This article introduces the use of computational simulation methods to develop aptamers and minimize the workload required for screening and optimizing aptamers. Various methods, including conformational structure prediction, molecular docking, and molecular dynamic simulation, were investigated for the estimation of aptamer-target molecule binding. In addition, examples of machine learning and deep learning technologies used to predict the binding of targets and ligands in the development of new drugs are introduced. This review will be helpful in the development and application of in silico aptamer screening and characterization.

Summary: The specific aptamer PS-ZL-7c developed through Cell-SELEX technology showed high selectivity to drug-resistant HCC cells with dissociation constants in the nanomolar range. In vivo imaging results demonstrated the aptamer's potential as a targeting ligand for precise diagnosis and theranostics of multidrug-resistant HCC, as it specifically accumulated in drug-resistant tumors but not in drug-sensitive tumors and normal tissues.

Summary: Aptamers, single-strand oligonucleotides with binding capability to specific target molecules, are increasingly used in analysis, diagnosis, and medical treatment. However, conventional SELEX methods have limitations, leading to restricted applications of aptamers. Microfluidic technologies offer promise for rapid and high throughput aptamer selection due to their low cost, high speed, and automation advantages.

Summary: Aptamers, nucleic acid analogs of antibodies, have been extensively used for their specific and sensitive binding to target molecules, promising as diagnostic and therapeutic tools. To reduce the time and cost of aptamer synthesis and selection, computational approaches have been introduced. In this study, a simple sequence-based method was used to design a stable aptamer with potential binding properties to the target receptor.

Summary: A newly developed light-up RNA aptamer, RhoBAST, enables super-resolution imaging with single-molecule localization microscopy, surpassing the limitation of photobleaching. The intermittent fluorescence emission of RhoBAST allows for high-resolution imaging of RNA subcellular structures in live and fixed cells with precise localization and high signal-to-noise ratio.
