- Cell Biology
Background:
- Taxis, the directed movement of cells and microorganisms, is crucial for biological functions and disease understanding.
- Thermotaxis (response to temperature) and chemotaxis (response to chemicals) are key examples of taxis.
- Microfluidics offers advanced tools for studying cellular taxis at the microscale.
Purpose of the Study:
- To review recent advancements in microfluidic devices for thermotaxis and chemotaxis experiments.
- To explore microfluidic applications inspired by taxis phenomena, such as thermocapillarity and chemocapillarity.
- To bridge the gap between in vitro and in situ biological assays using microfluidic platforms.
Main Methods:
- Review of current literature on microfluidic chip development for taxis research.
- Categorization of microfluidic devices used in or inspired by thermotaxis and chemotaxis.

822
Chemotaxis in Escherichia coli is a sensory-driven motility mechanism that enables bacteria to navigate chemical gradients, moving toward beneficial environments while avoiding harmful conditions. This process relies on a signal transduction system integrating external chemical cues with flagellar motor control.Chemoreceptors and Signal DetectionE. coli detects chemical gradients through methyl-accepting chemotaxis proteins (MCPs), which are membrane-bound chemoreceptors that sense attractants...

01:21Chemotaxis and Direction of Cell Migration
4.7K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

1.5K
In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.
