The protocol presents the optimized parameters for preparing thermosensitive liposomes using the staggered herringbone micromixer microfluidics device. This also allows co-encapsulation of doxorubicin and indocyanine green into the liposomes and the photothermal-triggered release of doxorubicin for controlled/triggered drug release.

Source: Laboratory of Dr. Dana Lashley - College of William and Mary Demonstration by: Matt Smith When new bonds are formed in the course of a chemical reaction, it requires that the involved species (atoms or molecules) come in very close proximity and collide into one another. The collisions between these species are more frequent and effective the higher the speed at which these molecules are moving. A widely used rule of thumb, which has its roots in the Arrhenius equation1, states that...

Chemical Kinetics The reaction rate is the speed at which a chemical reaction occurs. The reaction rate is defined as the change in concentration of a component in the reaction with time. The speed of a reaction depends on several factors, including the concentration of reactants and the temperature at which the reaction is performed. Each reactant contributes to the speed of the reaction by a specific factor. This relationship is defined by the reaction rate law. Rate Law The rate law is an...

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University Today's modern world requires the use of a large amount of energy. While we harness energy from fossil fuels such as coal and oil, these sources are nonrenewable and thus the supply is limited. To maintain our global lifestyle, we must extract energy from renewable sources. The most promising renewable source, in terms of abundance, is the sun, which provides us with more than enough solar energy to fully fuel our...
FAQs
Temperature changes molecular motion and enzyme activity, which can alter the rates of biological reactions. At sufficiently extreme conditions, however, the same sensitivity can become damaging as proteins lose structure, membranes change fluidity, and cells struggle to maintain homeostasis. This contrast explains why temperature-response studies examine both functional performance and the limits imposed by environmental stress.
Enzyme activity provides one important route through which temperature affects biological function because reaction rates shift as molecular motion changes. Measurements can therefore connect temperature conditions with metabolism, growth, or development. Comparing these responses also reveals whether a biological system continues performing its functions or approaches conditions that produce physiological stress.
These components show that temperature sensitivity operates at several biological levels rather than through reaction rates alone. Changes in protein structure can impair molecular function, while altered membrane fluidity can disturb cellular organization. Together, such effects challenge homeostasis, the maintenance of stable internal conditions, and help explain why extreme temperatures can affect survival and organismal performance.
Researchers use temperature-response measurements to relate temperature conditions to outcomes such as reaction activity, metabolism, growth, development, stress physiology, or microbial activity. The selected outcome determines which part of the biological response is evaluated. These measurements provide a basis for identifying functional changes, stress responses, and patterns that may help explain adaptation to environmental variation.
Temperature-response analyses help researchers examine how organisms respond to seasonal variation and environmental extremes. Those results can support predictions about species responses to climate change by linking temperature conditions with function, stress, and survival-related processes. They also help explain why ecological distributions may change when thermal conditions alter organismal performance.
The effects of temperature extend beyond individual physiology. Temperature-response information can support studies of disease transmission by showing how biological activity changes under different conditions, while measurements of microbial activity help clarify consequences for ecosystem processes. This broader context connects molecular and cellular responses with changes occurring across organisms, populations, and ecosystems.
