Prof. Dr. Leonhard Möckl

Leonhard Möckl studierte Chemie und Biochemie an der LMU München. Er promovierte 2015 mit einer Arbeit über die Rolle der Glycocalyx in der Organisation von Membranproteinen. Im Jahr 2016 wechselte er in das Labor von W.E. Moerner an der Stanford University, wo er Einzelmolekültechniken zur Untersuchung der Glycocalyx einsetzte und darüber hinaus Deep-Learning-basierte Ansätze für Einzelmolekülstudien entwickelte. Im Jahr 2020 wurde unabhängiger Gruppenleiter am MPL. Seit 2024 hat er die Professur für Nano-optische Bildgebung an der FAU inne, die am neu gegründeten CITABLE angesiedelt ist.

In seiner Freizeit liest er, spielt Klavier, wandert oder spielt Volleyball.

Automated discovery of experimental designs in super-resolution microscopy with XLuminA

Nature Communications 15 10658 (2024) | Journal | PDF

Driven by human ingenuity and creativity, the discovery of super-resolution techniques, which circumvent the classical diffraction limit of light, represent a leap in optical microscopy. However, the vast space encompassing all possible experimental configurations suggests that some powerful concepts and techniques might have not been discovered yet, and might never be with a human-driven direct design approach. Thus, AI-based exploration techniques could provide enormous benefit, by exploring this space in a fast, unbiased way. We introduce XLuminA, an open-source computational framework developed using JAX, a high-performance computing library in Python. XLuminA offers enhanced computational speed enabled by JAX’s accelerated linear algebra compiler (XLA), just-in-time compilation, and its seamlessly integrated automatic vectorization, automatic differentiation capabilities and GPU compatibility. XLuminA demonstrates a speed-up of 4 orders of magnitude compared to well-established numerical optimization methods. We showcase XLuminA’s potential by re-discovering three foundational experiments in advanced microscopy, and identifying an unseen experimental blueprint featuring sub-diffraction imaging capabilities. This work constitutes an important step in AI-driven scientific discovery of new concepts in optics and advanced microscopy.

Tailored Bisacylphosphane Oxides for Precise Induction of Oxidative Stress-Mediated Cell Death in Biological Systems

Karim Almahayni, Jana Bachir Salvador, Riccardo Conti, Anna Widera, Malte Spiekermann, Daniel Wehner, Hansjörg Grützmacher, Leonhard Möckl

ACS Chemical Biology 20 77-85 (2024) | Journal | PDF

Precise cell elimination within intricate cellular populations is hampered by issues arising from the multifaceted biological properties of cells and the expansive reactivity of chemical agents. Current chemical platforms are often limited by their complexity, toxicity, and poor physical/chemical properties. Here, we report on the synthesis of a structurally versatile library of chemically tunable bisacylphosphane oxides (BAPOs), which harnesses the spatiotemporal precision of light delivery, thereby establishing a universal strategy for on-demand, precise cellular ablation in vitro and in vivo.

A paintbrush for delivery of nanoparticles and molecules to live cells with precise spatiotemporal control

Cornelia Holler, Richard W. Taylor, Alexandra Schambony, Leonhard Möckl, Vahid Sandoghdar

Nature Methods 21 512-520 (2024) | Journal | PDF

Delivery of very small amounts of reagents to the near-field of cells with micrometer spatial precision and millisecond time resolution is currently out of reach. Here we present μkiss as a micropipette-based scheme for brushing a layer of small molecules and nanoparticles onto the live cell membrane from a subfemtoliter confined volume of a perfusion flow. We characterize our system through both experiments and modeling, and find excellent agreement. We demonstrate several applications that benefit from a controlled brush delivery, such as a direct means to quantify local and long-range membrane mobility and organization as well as dynamical probing of intercellular force signaling.

Precise cell elimination within intricate cellular populations is hampered by issues arising from the multifaceted biological properties of cells and the expansive reactivity of chemical agents. Current platforms are often limited by their complexity, toxicity, and poor physical/chemical properties. Here, we integrate the spatio-temporal precision of light delivery and the structural versatility of bisacylphosphane oxides (BAPOs), establishing a universal strategy for on-demand, precise cellular ablation in vitro and in vivo.
