Instability and self-propulsion of flexible autophoretic filaments
Ursy Makanga, Akhil Varma, Panayiota Katsamba
Over the past decade, autophoretic colloids have emerged as a prototypical system for studying self-propelled motion at microscopic scales, with promising applications in microflui…
Elastohydrodynamics of 3D chemically active filaments
Matthew D Butler, Benjamin J Walker, Thomas Montenegro-Johnson +1
Active deformable filaments exhibit a large range of qualitatively different three-dimensional dynamics, depending on their flexibility, the strength and nature of the active forci…
Slender Phoretic Loops and Knots
Panayiota Katsamba, Matthew D. Butler, Lyndon Koens +1
We present an asymptotic theory for solving the dynamics of slender autophoretic loops and knots. Our formulation is valid for non-intersecting 3D centrelines, with arbitrary chemi…
Slender Phoretic Theory of chemically active filaments
Panayiota Katsamba, Sébastien Michelin, Thomas D. Montenegro-Johnson
Artificial microswimmers, or "microbots" have the potential to revolutionise non-invasive medicine and microfluidics. Microbots that are powered by self-phoretic mechanisms, such a…
Selectively Controlled Magnetic Microrobots with Opposing Helices
Joshua Giltinan, Panayiota Katsamba, Wendong Wang +2
Magnetic microrobots that swim through liquid media are of interest for minimally invasive medical procedures, bioengineering, and manufacturing. Many of the envisaged applications…
Propulsion by stiff elastic filaments in viscous fluids
Panayiota Katsamba, Eric Lauga
Flexible filaments moving in viscous fluids are ubiquitous in the natural microscopic world. For example, the swimming of bacteria and spermatozoa as well as important physiologica…
Adaptive locomotion of artificial microswimmers
Henwei Huang, Fazil Emre Uslu, Panayiota Katsamba +4
Bacteria can exploit mechanics to display remarkable plasticity in response to locally changing physical and chemical conditions. Compliant structures play a striking role in their…
Hydrodynamics of bacteriophage migration along bacterial flagella
Panayiota Katsamba, Eric Lauga
Bacteriophage viruses, one of the most abundant entities in our planet, lack the ability to move independently. Instead, they crowd fluid environments in anticipation of a random e…
