Bioengineering DNA for Carbon Nanotube Sensors

Ardemis Anoush Boghossian, Yahya Rabbani

Single-walled carbon nanotubes (SWCNTs) generate near-infrared fluorescence that is useful for biomedical and environmental optical sensing. They can be colloidally suspended by π-electron-rich biopolymers like DNA that self-assemble onto their surfaces. T ...

Cation Pretreatment Enables the Saline Stability of a Near-Infrared Sensor for Dopamine

Ardemis Anoush Boghossian, Hanxuan Wang

Single-walled carbon nanotubes (SWCNTs) are wrapped with single-stranded DNA (ssDNA) to create near-infrared (NIR-II) fluorescent sensors for diverse analytes. However, the interaction between the negatively charged backbone of ssDNA and cations in biologi ...

Micropreparative Gel Electrophoresis for Purification of Nanoscale Bioconjugates

Ardemis Anoush Boghossian, Yahya Rabbani, Shang-Jung Wu, Vitalijs Zubkovs, Sayyed Hashem Sajjadi

Conventional techniques for purifying macromolecular conjugates often require complex and costly installments that are inaccessible to most laboratories. In this work, we develop a one-step micropreparative method based on a trilayered polyacrylamide gel e ...

Prediction of mycotoxin response of DNA-wrapped nanotube sensor with machine learning

Ardemis Anoush Boghossian, Yahya Rabbani, Sayyed Hashem Sajjadi

DNA-wrapped single-walled carbon nanotubes (DNA-SWCNTs) have demonstrated great versatility as optical sensors. SWCNTs emit a near-infrared fluorescence that is responsive to the slightest changes in their environment, enabling the creation of sensors that ...

Extracellular electron transfer pathways to enhance the electroactivity of modified Escherichia coli

Ardemis Anoush Boghossian, Melania Reggente, Mohammed Mouhib, Nils Schürgers

Escherichia coli (E. coli) show limited extracellular electron transfer (EET) that compromises their use in bioelectronics. We enhance the EET in E. coli by expressing an electron transfer pathway that spans the inner and outer membranes of the cell, inclu ...
