Aptamers and aptamer targeted delivery [PDF]
RNA Biology, 2009 When aptamers first emerged almost two decades ago, most were RNA species that bound and tagged or inhibited simple target ligands. Very soon after, the 'selectionologists' developing aptamer technology quickly realized more potential for the aptamer.

International Journal of Molecular Sciences, 2017 Aptamers are short nucleic acid sequences capable of specific, high-affinity molecular binding. They are isolated via SELEX (Systematic Evolution of Ligands by Exponential Enrichment), an evolutionary process that involves iterative rounds of selection and amplification before sequencing and aptamer characterization.

Nucleic Acids Research, 2004 The aptamer database is designed to contain comprehensive sequence information on aptamers and unnatural ribozymes that have been generated by in vitro selection methods. Such data are not normally collected in 'natural' sequence databases, such as GenBank.

Aptamer and aptamer pharmaceuticals [PDF]
SCIENTIA SINICA Chimica, 2018 Recently, molecule-based targeted therapy has achieved remarkable success in clinical, and opened up a new era particulraly in the field of cancer therapy. Monoclonal antibodies and small molecule inhibitors are two pillars of this field. Additionally, a single-strand nucleic acid molecule called “chemical antibody” has also attracted increasing ...

Electrochemical Aptasensor for Detection of Dopamine [PDF]
, 2020 This work presents a proof of concept of a novel, simple, and sensitive method of detection of dopamine, a neurotransmitter within the human brain. We propose a simple electrochemical method for the detection of dopamine using a dopamine-specific aptamer

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

Community sewage sensors towards evaluation of drug use trends: detection of cocaine in wastewater with DNA-directed immobilization aptamer sensors [PDF]
, 2016 Illicit drug use has a global concern and effective monitoring and interventions are highly required to combat drug abuse. Wastewater-based epidemiology (WBE) is an innovative and cost-effective approach to evaluate community-wide drug use trends ...

Aptamer-based cocaine assay using a nanohybrid composed of ZnS/Ag2Se quantum dots, graphene oxide and gold nanoparticles as a fluorescent probe [PDF]
, 2020 Authors report on a new fluoro-graphene-plasmonic nanohybrid aptamer-based fluorescent nanoprobe for cocaine. To construct the nanoprobe, newly synthesized glutathione-capped ZnS/Ag 2Se quantum dots (QDs) were first conjugated to graphene oxide (GO) to ...

Selective Targeting to Glioma with Nucleic Acid Aptamers [PDF]
, 2015 Malignant glioma is characterised by a rapid growth rate and high capacity for invasive infiltration to surrounding brain tissue; hence, diagnosis and treatment is difficult and patient survival is poor.
