Novel Nano- and Biophotonics

Light is one of the most versatile tools known to mankind. Prof. Gather develops nano and micro scale devices that combine light and soft materials to facilitate paradigm shifts in biological understanding and contribute new tools for medical research.

Research Focus

Stimulation probe with 1024 individually addressable organic LED light sources for optogenetic stimulation in the brain [Nature Electronics (2023)]

Research in the life sciences often evolves around specific questions related to the understanding of processes, pathways and mechanisms. However, historically important paradigm shifts in understanding were often triggered by methodological advances in chemistry or physics. An important example is the development of in situ and in vivo imaging tools, as evidenced by three recent Nobel Prizes in Chemistry (2008, 2014, 2017). With this in mind, my team at the Humboldt Centre for Nano- and Biophotonics (HCNB) aims to perform and catalyse world-class research on nano and micro scale photonic devices and microscopy modalities that provide biosensing, bioimaging and biomodulation functionalities not available with existing technology. We then deploy these tools, frequently in close collaboration with other investigators at CECAD, to further advance ongoing and future research on aging and aging-associated diseases.

By squeezing electromagnetic waves into microscopic volumes and letting them interact with a range of ‘interesting’ materials, such as ultra-soft jellies, glowing proteins, or organic semiconductors, my team performs biosensing, bioimaging and biomodulation in unprecedented ways.

Our Goals

Illustration of the cell implanted laser concept. The unique spectrum of each implanted laser acts as optical barcode to identify individual cells amongst thousands or even billions of other cells.

My team and I work on a range of models and diseases of specific relevance to CECAD.

For instance, we develop tools for optogenetic control of neuronal activity through photonic implants with organic LEDs. We also further advance cell force microscopy (e.g. to study keratinocyte differentiation, mechanical aspects of podocyte injury, forces during the invasion of cancer cells through the ECM, and contractility of cardiac cells and tissue).
Another field of great interest is biologically integrated microlasers which we use as barcodes for cell tracking and as miniature sensors for local changes in cell density and cell force.
