In vivo polydopamine coating of Rhodobacter sphaeroides for enhanced electron transfer

Ardemis Anoush Boghossian, Melania Reggente

Recent advances in coupling light-harvesting microorganisms with electronic components have led to a new generation of biohybrid devices based on microbial photocatalysts. These devices are limited by the poorly conductive interface between phototrophs and ...

Spinning-disc confocal microscopy in the second near-infrared window (NIR-II)

Ardemis Anoush Boghossian, Alessandra Antonucci, Benjamin Paul Johanès Gabriel Lambert, Vitalijs Zubkovs

Fluorescence microscopy in the second near-infrared optical window (NIR-II, 1000–1350 nm) has become a technique of choice for non-invasive in vivo imaging. The deep penetration of NIR light in living tissue, as well as negligible tissue autofluorescence w ...

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

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

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 ...

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

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

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 ...

Carbon nanotube uptake in cyanobacteria for near-infrared imaging and enhanced bioelectricity generation in living photovoltaics

Ardemis Anoush Boghossian, Alice Judith Gillen, Vitalijs Zubkovs, Alessandra Antonucci, Benjamin Paul Johanès Gabriel Lambert, Nils Schürgers, Melania Reggente, Charlotte Elisabeth Marie Roullier, Mohammed Mouhib

Single-walled carbon nanotubes (SWCNTs) have unique optoelectronic properties that make them suitable for applications ranging from phototherapy to imaging and sensing, but their uptake has mainly been explored in eukaryotic cells. Here the authors explore ...

Plasmon-induced near-infrared fluorescence enhancement of single-walled carbon nanotubes

Giulia Tagliabue, Ardemis Anoush Boghossian, Shang-Jung Wu, Alessandra Antonucci, Theodoros Tsoulos, Amirmostafa Amirjani, Sayyed Hashem Sajjadi

Single-walled carbon nanotubes (SWCNTs) emit near-infrared (NIR) fluorescence that is ideal for optical sensing. However, the low quantum yields diminish the sensor’s signal-to-noise ratio and limits the penetration depths for in vivo measurements. In this ...

Directed evolution of the optoelectronic properties of synthetic nanomaterials

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

Directed evolution is a powerful approach to tailor protein properties toward new or enhanced functions. Herein, we use directed evolution to engineer the optoelectronic properties of DNA-wrapped single-walled carbon nanotube sensors through DNA mutation. ...
