Based on gold nanoparticles (AuNPs) and engineered DNA aptamers, we designed a novel bioassay strategy for the detection of adenosine as a small target molecule. In this design, an aptamer is engineered to consist of two pieces of random-coil like ssDNA which are respectively attached to AuNPs through their 5'-thiol-modified end. They can reassemble into(More)
Based on the adsorption performance of composite microspheres with activated carbon (AC) and sodium alginate (SA), as well as the magnetic property of Fe₃O₄, we designed and explored an efficient strategy to prepare a unique, multifunctional Fe₃O₄/AC/SA composite absorbent (MSA-AC) that extracted dye from aqueous solution. The composite exhibited the(More)
Terminators in eukaryotes play an important role in regulating the transcription process by influencing mRNA stability, translational efficiency, and localization. Herein, the strengths of 100 natural terminators in Saccharomyces cerevisiae have been characterized by inserting each terminator downstream of the TYS1p-enhanced green fluorescent protein (eGFP)(More)
