Epidermal growth factor receptor (EGFR) is a cell surface protein overexpressed in
cancerous cells. It is known to be the most common oncogene. EGFR concentration also …

In this paper, we report a “signal-on” electrochemical aptasensor for simultaneous
determination of two tumor markers MUC1 and VEGF165, by using a ferrocene-labeled …

Aptamers are specific oligonucleotides selected invitro which bind to target molecules with
high affinity and specificity like antibody-antigen interactions. For that reason, these synthetic …

It has been more than two decades since aptamer and the systematic evolution of ligands by
exponential enrichment (SELEX) method were discovered by Larry Gold and Andrew …

Recent advances in nanotechnology have enabled the development of nanoscale sensors
that outperform conventional biosensors. This review summarizes the nanoscale biosensors …

Since the introduction by Gold et al. in 1990, nucleic acid aptamers had evolved to become
a true contender in biosensors for protein and cell detections. Aptamers are short strands of …

The detection of early-stage cancer offers patients the best chance of treatment and could
help reduce cancer mortality rates. However, cancer cells or biomarkers are present in …

We report here that a hairpin-structured DNA that possesses an anti-ATP aptamer sequence
successfully detected target ATP or adenosine in a temperature-dependent manner by …

Nano‐biosensors that are composed of recognition molecules and nanomaterials have
been extensively utilized in disease diagnosis, health management, and environmental …

Electrochemical aptasensor has been broadly advanced for nucleic acid detection.
However, it is a long-term goal to design an aptasensor with high specificity, flexibility, and …
