Introduction to cell biophysics

Also listed as: מבוא לביופיזיקה של התא

Membrane mechanics, molecular motors and the cytoskeleton. It is the physics layer under a cell-mechanics thesis, and it is research-facing rather than design-facing.

Opens up

  • Cell mechanics research

What it covers

Topics

  • Membrane mechanics and transport
  • Molecular motors and force generation
  • Cytoskeletal mechanics
  • Polymer physics of biological filaments
  • Experimental methods at the single-molecule scale

Results worth carrying out

  • Helfrich bending energy

    E=[12κ(C1+C2C0)2+κˉC1C2]dAE = \int \left[\tfrac{1}{2}\kappa\left(C_1 + C_2 - C_0\right)^2 + \bar{\kappa}\,C_1 C_2\right] dA
  • Motor force–velocity relation

    v=v0(1FFstall)v = v_0\left(1 - \frac{F}{F_{\text{stall}}}\right)
  • Persistence length

    p=κkBT\ell_p = \frac{\kappa}{k_B T}

This map tells you what a course contains. The summaries, the tutoring and the people who already took it are the part you get by joining.

The topic outlines are not official syllabi. The university publishes a catalogue blurb per course, not lecture-by-lecture material, so each outline describes what a course of that name, at those hours, with those prerequisites teaches at engineering schools generally, cross-checked against the standard textbook for the subject. Treat it as an informed map, not as a transcript of the lectures.
