Aptamers continue to demonstrate advantages in platforms and applications which require specific detection of small molecule targets.
There has been a growth in the use of point of care devices across a range of applications and assay types due to a need for rapid and reliable analysis (Vashist 2017). Aptamers are perfectly suited for […]

Scientists from the Technical University of Denmark, led by Krishna Kant have published a new review in Biotechnology Advances including aptamer-based approaches for the rapid detection of food-borne pathogens.
Food borne diseases, caused by the consumption of foods contaminated with pathogens or their toxins, are one of the major burdens to public health, causing […]

Changes in hormone levels can be key indicators to a variety of issues, examples include testosterone levels in general health and well being(1) and diagnosing Cushing’s disease involving the steroid cortisol (2). While these small molecules and others are well documented and their role in health and disease is becoming better understood, researchers […]

Last week we began to discuss how aptamers can be used in biosensors. If you missed this, you can read it here.
Today we outline two more strategies for utilising aptamers in biosensors.
Target Induced Displacement Mode
Target Induced Displacement (TID) mode uses an aptamer anchored via a complementary oligo, localising the target binding aptamer. When […]
Aptamers are increasingly being used in Biosensors. Biosensors are devices that use biological molecules, especially enzymes or antibodies, or living organisms to detect the presence of an analyte. By modifying an aptamer with an appropriate reporter group, we are able to develop biosensors that measure analytes qualitatively and/or quantitatively.
Modes in which aptamers are utilised […]
