Thermal properties of lipid bilayers derived from the transient heating regime of upconverting nanoparticles

Abstract

Heat transfer and thermal properties at the nanoscale can be challenging to obtain experimentally. These are potentially relevant for understanding thermoregulation in cells. Experimental data from the transient heating regime...

Heat transfer and thermoregulation within single cells revealed by transient plasmonic imaging

“…Usually, the characteristic time scale of heat dissipation and the thermal conduction property of the medium can be approximated in an inverse proportion. 29,30,35 We then consider Article the nanolens that consists of nanoparticle and interfacial hot layer as the heated body, and the evolution of nanolens could be expressed by:…”

How to calibrate luminescent crossover thermometers: a note on “quasi”-Boltzmann systems

“…1–3 Its potential as a local non-invasive temperature probe has been shown in several niche applications ranging from catalysis 4,5 over biological processes 6 to heat transport phenomena at the micro-and nanoscale. 7–9…”

“…[1][2][3] Its potential as a local non-invasive temperature probe has been shown in several niche applications ranging from catalysis 4,5 over biological processes 6 to heat transport phenomena at the micro-and nanoscale. [7][8][9] Various readout options exist such as the intensity of a signal, the luminescence decay time, width, or position of an emission band. Among the different methodological concepts, [10][11][12] especially the ratiometric intensity approach exploiting the emission from two thermally coupled excited levels has become popular due to its simplicity and possibility for the fast readout (by the usage of sensitive CCD cameras for example).…”

Cellular Thermometry Considerations for Probing Biochemical Pathways

“…Spatial distribution of the local thermal interfacial resistances can be known if spatial temperature distributions can also be measured across the cellular medium. Recent studies [59], [76] have measured the thermal properties of the lipid bilayers in cell membranes; however, measurements on cytoskeleton components such as actin, microtubules, intermediate filaments, etc. are necessary to understand the significance of their thermal interfacial resistance.…”
