diffusiotactic
Diffusiotaxis is a form of taxis in which cells or motile particles migrate in response to a gradient of a diffusing chemical substance. The gradient typically arises from diffusion of a solute from a localized source, creating spatial variation in concentration that organisms can sense and use to direct movement. Positive diffusiotaxis refers to movement toward higher concentrations, while negative diffusiotaxis describes movement away from them.
Mechanistically, diffusiotaxis involves sensing local chemical concentration through receptors or signaling pathways and translating that information
Applications and relevance include understanding microbial foraging strategies, biofilm formation, and the behavior of synthetic active
Terminology usage varies in the literature, and some authors describe diffusion-driven gradients under different labels. Nevertheless,
