RESEARCH DESCRIPTION

The Landry Lab's work develops synthetic bio-mimetic nanocomposites to impart control over nanomaterial interactions with biological systems for two applications: 1) to exploit the intrinsic nanomaterial infrared fluorescence for molecular imaging, and 2) to exploit the highly tunable chemical and physical properties of nanomaterials for targeted delivery of biological cargoes.

Molecular Imaging: The importance of monitoring neurotransmission is relevant to our understanding of neuropsychiatric disease, in which 'neurochemical imbalances' are at the core of many psychiatric and neurodegenerative disorders such as depression, anxiety, Alzheimer's disease, Parkinson's disease, and social autism spectrum disorder. Her lab develops optical probes for neuromodulators such as dopamine, serotonin, and norepinephrine. Aberrant neuromodulator signaling in the brain has been implicated in various psychiatric and neurodegenerative disorders, whereby many drugs target neuromodulator signaling. They implement their optical probes for neuromodulators such as dopamine (Beyene et al. Science Advances 2019) and serotonin (Jeong et al. Science Advances 2019) to study addiction, Huntington's Disease, and Parkinson's Disease, among others.

Targeted bio-delivery: The Landry Lab also develops nanoscale particles that enable grafting and delivery of biomolecular cargoes (DNA, RNA, protein) to plants. Despite the importance of creating transgenic plants, plant systems remain difficult to genetically transform because of the unique presence of the plant cell wall, which poses the dominant barrier to exogenous biomolecule delivery. The lab develops nanoparticle-based platforms to enable delivery of gene vectors and RNA (Demirer et al. Nature Nanotechnology 2019), and RNA (Zhang et al. PNAS 2019; Demirer et al. Science Advances 2020; Goh, Zhang et al. Nature Nanotechnology 2021) to agriculturally-relevant plants such as arugula, wheat, and cotton. Biomolecule delivery to plants can assist in plant and crop genetic engineering can solidify the agricultural industry by conferring desirable traits to plants such as increased yield, abiotic stress tolerance, and disease and pest resistance. Production of transgenic plants with nanoparticle-based DNA delivery, without trasngene integration (Demirer et al. Nature Protocols 2019; Demirer, Zhang et al. Nature Protocols 2020), can address the need for sustainable and high-yielding crops without the need to cross out transgenes. Specifically, their platform for delivery of Cas9 DNA vectors represents a platform by which to genetically modify plants without DNA integration (when delivering a DNA vector coding for CRISPR), or without DNA altogether (when delivering an RNP), potentially enabling gene-edited crops to circumvent the process of regulatory oversight as genetically modified organisms (GMOs) (Landry and Mitter, Nature Nanotechnology 2020; Demirer et al. Nature Nanotechnology 2021).
