Summary
Researchers developed an affordable, open-source temperature control system called ThermoCyte for live-cell imaging. This system ensures precise temperature regulation at physiological levels, making advanced cellular analysis more accessible.
Area of Science:
- Microscopy and Live-Cell Imaging
- Cell Biology
- Biotechnology
Background:
- Live-cell imaging is crucial for studying dynamic cellular processes like motility and signaling.
- Existing temperature control systems for live-cell imaging are often expensive and proprietary.
- There is a need for accessible, adaptable solutions for maintaining physiological conditions during imaging.
Purpose of the Study:
- To develop an inexpensive, open-source temperature control system for in vitro live-cell imaging.
- To enable precise temperature control and logging at physiological levels for cellular experiments.
- To provide a modular and adaptable tool for custom live-cell imaging protocols.
Main Methods:
- Construction of the 'ThermoCyte' system using standard electronic components.
- Implementation of precise tuning, control, and logging functionalities for temperature set points.
- Testing and validation of thermal stability and reliability over time.
Main Results:
- The ThermoCyte system demonstrated stable thermal dynamics with reliable temperature cycling.
- Achieved a low standard deviation of 0.42°C over a 1-hour period.
- The system is modular and adaptable to diverse research requirements.
Conclusions:
- The developed ThermoCyte system offers a simple, inexpensive, and reliable solution for live-cell imaging at physiological temperatures.

01:43Thermosensation
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
01:23Physical Methods for Controlling Microbial Growth: Temperature
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...
