Area Of Science
- Materials Science
- Biomedical Engineering

Background
- Organogels offer advantages over hydrogels, including better solvent compatibility and durability, but face challenges in biomedical applications due to toxicity and fabrication issues.
- Developing organogels with inherent therapeutic properties and anti-biofouling capabilities is crucial for advancing medical device technology.
Purpose Of The Study
- To create a mechanically durable, thermally and environmentally stable organogel using an amine-epoxy reaction.
- To incorporate a hydrophobic gasotransmitter therapeutic agent with antimicrobial and antithrombotic functions.
- To infuse the organogel with a lubricant for enhanced anti-biofouling properties and investigate its potential for medical applications.
Main Methods
- Utilized the amine-epoxy ring opening reaction for organogel fabrication.
- Tuned mechanical properties by adjusting cross-linker concentration.
- Loaded the organogel with a hydrophobic gasotransmitter therapeutic agent and a lubricant.
- Evaluated cytocompatibility, hemocompatibility, biomass accumulation resistance, protein adhesion resistance, and platelet repellence.
- Tested the organogel as coatings on various substrates (polymers, metals, glass).
Main Results
- Developed a mechanically durable, self-standing organogel with tunable properties.
- The organogel demonstrated significant resistance to biomass accumulation (>85%) and protein adhesion (>60%).
- Achieved high platelet repellence (>80%) and exhibited slippery characteristics with low water sliding angles (<10°) when used as coatings.
Conclusions
- This study presents a novel chemical approach for fabricating a durable, slippery organogel with integrated therapeutic and anti-biofouling functionalities.
- The developed organogel and its coatings show promising potential for applications in blood-contacting medical devices and anti-adhesion surfaces.
- The material's robustness, biocompatibility, and anti-biofouling performance address key limitations of current organogel technologies for biomedical use.

In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:
where:
O = observed values
E = expected values (which should be at least 5)
A test of independence determines whether...
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.
Let’s think of...
Effective lubrication between a rotating shaft and its bearing housing is essential in rotating machinery to minimize friction, wear, and energy loss. With carefully controlled thickness and viscosity, the lubricant layer prevents metal-to-metal contact, ensuring smooth operation.
To calculate the required thickness of the lubricant layer, the tangential velocity at the shaft's surface must first be determined. This velocity is calculated by converting the rotational speed to angular velocity...
