A general approach to high-yield biosynthesis of chimeric RNAs bearing various types of functional small RNAs for broad applications. [PDF]

open access: yes, 2015
RNA research and therapy relies primarily on synthetic RNAs. We employed recombinant RNA technology toward large-scale production of pre-miRNA agents in bacteria, but found the majority of target RNAs were not or negligibly expressed. We thus developed a

A novel colorimetric biosensor based on non-aggregated Au@Ag core–shell nanoparticles for methamphetamine and cocaine detection [PDF]

open access: yes, 2017
We report a novel colorimetric biosensor based on non-aggregation Au@Ag core-shell nanoparticles to detect methamphetamine and cocaine. The biosensor consisted of a reporter probe (RP) that is a specific single-stranded DNA (ssDNA) sequence coated on Au ...

Bioaffinity detection of pathogens on surfaces [PDF]

open access: yes, 2010
The demand for improved technologies capable of rapidly detecting pathogens with high sensitivity and selectivity in complex environments continues to be a significant challenge that helps drive the development of new analytical techniques. Surface-based

DNA Aptamers against Taiwan Banded Krait α-Bungarotoxin Recognize Taiwan Cobra Cardiotoxins

open access: yesToxins, 2016
Bungarus multicinctus α-bungarotoxin (α-Bgt) and Naja atra cardiotoxins (CTXs) share a common structural scaffold, and their tertiary structures adopt three-fingered loop motifs. Four DNA aptamers against α-Bgt have been reported previously.

Development of DNA aptamer selection approach based on membrane ultrafiltration of aptamer/target complex

open access: yesActa Biomedica Scientifica, 2022
Background. Aptamers are small single-stranded DNA or RNA molecules that have an affinity for a specific target molecule. The main method of aptamers construction is the technology of systematic evolution of ligands with exponential enrichment (SELEX ...

Role of Exosomes in Cancer and Aptamer-Modified Exosomes as a Promising Platform for Cancer Targeted Therapy

open access: yesBiological Procedures Online
Exosomes are increasingly recognized as important mediators of intercellular communication in cancer biology. Exosomes can be derived from cancer cells as well as cellular components in tumor microenvironment.

Screening and Application of DNA Aptamers for Heparin-Binding Protein

open access: yesMolecules
Rapid detection of heparin-binding protein (HBP) is essential for timely intervention in sepsis cases. Current detection techniques are usually antibody-based immunological methods, which have certain problems, such as complexity and slow detection, and ...

Novel Cell type-specific aptamer-siRNA delivery system for HIV-1 therapy [PDF]

open access: yes, 2007
The successful use of small interfering RNAs (siRNAs) for therapeutic purposes requires safe and efficient delivery to specific cells and tissues. Here we demonstrate cell type-specific delivery of anti-HIV siRNAs via fusion to an anti-gp120 aptamer. The

Interplay between RNA‐protein interactions and RNA structures in gene regulation

open access: yesFEBS Open Bio, EarlyView.
Methodological advances in mapping transcriptome‐wide RNA‐protein interactions and RNA structures have started to uncover the potential of RNP conformations in gene regulation. Competing RNA–RNA, RNA‐protein and protein–protein interactions shape the compaction and function of RNPs throughout their lifetime and may provide novel therapeutic targets in ...

Carbon nanotube decorated magnetic microspheres as an affinity matrix for biomolecules [PDF]

open access: yes, 2013
Carbon nanotube (CNT) decorated magnetic microspheres were fabricated to develop a multimodal platform that utilizes non-covalent molecular interactions of CNTs to magnetically separate biomolecules.
