Summary
Hypothermal opto-thermophoretic tweezers (HOTTs) enable low-power, non-invasive trapping of cells and colloids. This novel method enhances thermophoretic forces at low temperatures, minimizing thermal damage for broader biotechnology applications.
Area of Science:
- Biotechnology
- Materials Science
- Nanotechnology
Background:
- Optical tweezers require high laser power and refractive index contrast, risking damage to biological samples.
- Optothermal tweezers use lower laser power but cause intense heating and require specific solution environments, limiting biological applications.
Conclusions:
- HOTTs offer a non-invasive and versatile platform for low-power trapping and manipulation.
- This technology is suitable for a wide range of biological applications and materials science.
- HOTTs present a promising tool for fundamental research and practical applications in biotechnology.

01:43Thermosensation
30.9K
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...

01:13Equipments Used to Measure Body Temperature
1.1K
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

01:14Assessing Body Temperature - Tympanic membrane
638
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

01:23Physical Methods for Controlling Microbial Growth: Temperature
171
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...
