Directed evolution of nanosensors for the detection of mycotoxins

Ardemis Anoush Boghossian, Benjamin Paul Johanès Gabriel Lambert, Alice Judith Gillen, Shang-Jung Wu, Afsaneh Taheri Telgari

In this study, we develop and apply a directed evolution approach to engineer the optical sensing properties of DNA-wrapped single-walled carbon nanotubes (DNA-SWCNTs) towards mycotoxins, a class of molecules critical to detect in the food industry. We suc ...

Distinguishing dopamine and calcium responses using XNA-nanotube sensors for improved neurochemical sensing

Ardemis Anoush Boghossian, Melania Reggente, Alice Judith Gillen, Alessandra Antonucci, Daniel Eduardo Morales Garza

To date, the engineering of single-stranded DNA-SWCNT (DNA-SWCNT) optical biosensors have largely focused on creating sensors for new applications with little focus on optimising existing sensors for in vitro and in vivo conditions. Recent studies have sho ...

Modulating the properties of DNA-SWCNT sensors using chemically modified DNA

Ardemis Anoush Boghossian, Benjamin Paul Johanès Gabriel Lambert, Alice Judith Gillen, Alessandra Antonucci, Daniel Molina Romero

Properties of SWCNT-based sensors such as brightness and detection capabilities strongly depend on the characteristics of the wrapping used to suspend the nanotubes. In this study, we explore ways to modify the properties of DNA-SWCNT sensors by us- ing ch ...

Synthetic Biology: A Solution for Tackling Nanomaterial Challenges

Ardemis Anoush Boghossian, Benjamin Paul Johanès Gabriel Lambert, Alice Judith Gillen

Bioengineers have mastered practical techniques for tuning a biomaterial’s properties with only limited information on the relationship between the material’s structure and function. These techniques have been quintessential to engineering proteins, which ...

Templating colloidal sieves for tuning nanotube surface interactions and optical sensor responses

Ardemis Anoush Boghossian, Benjamin Paul Johanès Gabriel Lambert, Daniel Jerôme Siefman, Alice Judith Gillen, Shang-Jung Wu

Surfactants offer a tunable approach for modulating the exposed surface area of a nanoparticle. They further present a scalable and cost-effective means for suspending single-walled carbon nanotubes (SWCNTs), which have demonstrated practical use as fluore ...

Enhancing bioelectricity generation in microbial fuel cells and biophotovoltaics using nanomaterials

Ardemis Anoush Boghossian, Melania Reggente, Mohammed Mouhib, Alice Judith Gillen, Alessandra Antonucci, Amirmostafa Amirjani

Microbial fuel cells and biophotovoltaics represent promising technologies for green bioelectricity generation. However, these devices suffer from low durability and efficiency that stem from their reliance on living organisms to act as catalysts. Such lim ...

Non-covalent Methods of Engineering Optical Sensors Based on Single-Walled Carbon Nanotubes

Ardemis Anoush Boghossian, Alice Judith Gillen

Optical sensors based on single-walled carbon nanotubes (SWCNTs) demonstrate tradeoffs that limit their use in in vivo and in vitro environments. Sensor characteristics are primarily governed by the non-covalent wrapping used to suspend the hydrophobic SWC ...
