Insights

Developing advanced taste sensors can improve pediatric medicine palatability. Optimizing membrane properties allows for sensors that mimic human taste perception, aiding drug formulation for children.

Area of Science:

  • Pharmaceutical Science
  • Biomedical Engineering
  • Sensory Science

Context:

  • Pediatric medicine palatability is a significant challenge in pharmaceutical development.
  • Children's heightened sensitivity to bitterness impacts medication adherence.
  • Volunteer efforts to deliver medicines to underserved areas highlight the need for palatable formulations.

Purpose:

  • To develop advanced taste sensors for the pharmaceutical industry.
  • To provide a "measure of taste" to aid in creating child-friendly drug formulations.
  • To overcome the challenge of bitter taste in pediatric medicines.

Summary:

  • Two novel methods were developed to control taste sensor characteristics by optimizing membrane electric density and hydrophobicity.
  • These methods enable the creation of advanced taste sensors meeting four key requirements: human-like taste threshold, consistent response, defined information units, and detection of taste interactions.
  • The developed taste sensors aim to replicate human taste perception for pharmaceutical applications.

Impact:

  • Facilitates the development of palatable pediatric drug formulations.
  • Enhances medication adherence and therapeutic outcomes in children.
  • Contributes to the advancement of taste sensing technology for broader pharmaceutical applications.

The Physiology of Taste01:24

The Physiology of Taste

The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

Taste Buds and Receptors01:20

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Gustation01:43

Gustation

Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

The Tongue and Taste Buds00:49

The Tongue and Taste Buds

The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Conditioned Taste Aversion01:14

Conditioned Taste Aversion

Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

G-Protein Gated Ion Channels01:21

G-Protein Gated Ion Channels

GPCRs are primarily responsible for our sense of smell, taste, and vision.  The binding of a sensory stimulus activates GPCR to stimulate effector proteins, many of which are ion channels in the sensory organs. GPCRs modulate the opening and closing of the target ion channels either directly by binding them, or by releasing second messengers that activate these channels. As ions move across the membrane, the membrane potential is altered, which induces an appropriate response.
