Temperature Measurement Sites

3.6K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Thermosensation01:43

Thermosensation

34.0K
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...

    Area of Science:

    • Nanotechnology
    • Biomedical Optics
    • Materials Science

    Background:

    • Upconversion nanoparticles (UCNPs) are promising for luminescence thermometry in biological tissues due to deep imaging and autofluorescence suppression.
    • Limitations include poor water solubility and weak luminescence, especially for small nanoparticles.
    • Conventional excitation at 980 nm causes significant water absorption and tissue overheating.

    Purpose of the Study:

    • To develop water-tolerant UCNPs with enhanced luminescence intensity and reduced thermal effects for optical temperature sensing.
    • To utilize neodymium (Nd+3) as a near-infrared absorber and sensitizer at a biocompatible excitation wavelength (808 nm).
    • To create a core/shell nanostructure for efficient energy transfer and improved performance.

    Main Methods:

    • Synthesis of YVO4:Er+3,Yb+3@Nd+3 core/shell nanoparticles with an average size of 20 nm.
    • Incorporation of Nd+3 into the core/shell structure to act as a sensitizer and near-infrared absorber.
    • Characterization of nanoparticle properties, including water tolerance, luminescence intensity, and temperature sensing capabilities.

    Main Results:

    • Successfully synthesized water-tolerant YVO4:Er+3,Yb+3@Nd+3 core/shell nanoparticles.
    • Achieved strong upconversion luminescence at a biocompatible excitation wavelength (808 nm).
    • Demonstrated minimized overheating in aqueous environments, crucial for biological applications.

    Conclusions:

    • The developed Nd+3-sensitized core/shell UCNPs offer a promising platform for advanced luminescence thermometry in biological tissues.
    • The use of 808 nm excitation significantly reduces thermal damage compared to traditional 980 nm excitation.
    • These nanoparticles exhibit enhanced water solubility and luminescence intensity, overcoming key limitations for in vivo applications.
