Universal Dynamic DNA Assembly-Programmed Surface Hybridization Effect for Single-Step, Reusable, and Amplified Electrochemical Nucleic Acid Biosensing

The traditional sensitive electrochemical biosensors are commonly confronted with the cumbersome interface operation and washing procedures and the inclusion of extra exogenous reagents, which impose the challenge on the detection simplicity, reliability, and reusability. Herein, we present the proof-of-principle of a unique biosensor architecture based on dynamic DNA assembly programmed surface hybridization, which confers the single-step, reusable, and enzyme-free amplified electrochemical nucleic acid analysis. To demonstrate the fabrication universality three dynamic DNA assembly strategies including DNA-fueled target recycling, catalytic hairpin DNA assembly, and hybridization chain reaction were flexibly harnessed to convey the homogeneous target recognition and amplification events into various DNA scaffolds for the autonomous proximity-based surface hybridization. The current biosensor architecture features generalizability, simplicity, low cost, high sensitivity, and specificity over the traditional nucleic acid-related amplified biosensors. The lowest detection limit of 50 aM toward target DNA could be achieved by hybridization chain reaction-programmed surface hybridization. The reliable working ability for both homogeneous solution and heterogeneous inteface facilitates the target analysis with a robust reliability and reproducibility, also making it to be readily extended for the integration with the kinds of detecting platforms. Thus, it may hold great potential for the biosensor fabrication served for the point-of-care applications in resource constrained regions

An Improved and Practical Synthesis of Tranexamic Acid

Tranexamic acid <b>1</b>, a synthetic antifibrinolytic drug with the treatment being considered highly cost-effective in many countries, has been included in the WHO list of essential medicines. In this paper, we designed the synthesis of <b>1</b> via a novel seven-step route from the readily available starting material dimethyl terephthalate, performing with 99.6% purity in 59.2% overall yield. During the process, we successfully developed a direct and efficient method for the preparation of key intermediate methyl 4-(acetamidomethyl)­benzoate by one-pot hydrogenation and acylation in acetic anhydride using Ni/Al₂O₃ as a catalyst. More importantly, it should be a straightforward and practical way to circumvent the usage of toxic reagents (CrO₃, Cl₂), solvent (CCl₄), and expensive catalyst (PtO₂), etc., that plagued the previous methodologies
