Thermosensation

Thermosensation

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...

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Chirality in Nature

Chirality in Nature

Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

Background:

Chitin, a natural polymer, can be dissolved and functionalized using NaOH/urea solvent.
Acrylamide-modified chitin (AMC) exhibits water solubility and responds to pH and ions.
Previous research established AMC's responsiveness to pH and cationic ions.

Purpose of the Study:

To investigate the thermosensitive properties of acrylamide-modified chitin (AMC).
To explore the factors influencing AMC's sol-gel transition temperature.
To assess the potential of AMC in temperature-responsive applications.

Main Methods:

Functionalization of chitin with acrylamide in NaOH/urea.
Characterization of AMC's sol-gel transition behavior.
Evaluation of factors affecting transition temperature, including degree of substitution, pH, concentration, and ionic environment.

Main Results:

AMC exhibits tunable sol-gel transition temperatures.
Transition temperature is influenced by degree of substitution, pH, polymer concentration, and ion presence.
AMC can form a hydrogel at 37 °C and revert to solution at 4 °C.

Conclusions:

Acrylamide-modified chitin (AMC) demonstrates tunable thermosensitive hydrogel formation.
AMC's properties can be modulated by various experimental parameters.
AMC shows promise for injectable materials and smart drug delivery systems.
