Contact lenses are explicitly designed optical devices that can be worn directly on the cornea of the eye. People with poor eyesight wear contact lenses, which helps to refocus oncoming light rays on the retina to achieve a clear vision. Contact lenses increase or decrease the focusing potential of the cornea, and thereby directly project light onto the retina and aid in treating refractive errors.
A recently developed laboratory-created material imitates human tissue and has the potential to decrease or substitute for the utilization of animal-derived components in biomedical studies.
Researchers from North Carolina State University have devised a nontoxic method for creating cellulose gels, drawing inspiration from the nest-building process of small birds.
Prosthetics moved by thoughts. Targeted treatments for aggressive brain cancer. Soldiers with enhanced vision or bionic ears.
The biofilm-forming bacteria E. coli adheres firmly to hydrophobic and hydrophilic protein-adsorbing self-assembling monolayers (SAMs) and weakly to hydrophilic protein-resisting SAMs, uncovered a recent study by Tokyo Tech researchers.
Researchers have discovered five genetic variations that, the longer a person attends school, increase their risk of developing nearsightedness. These results were published on November 17th, 2022 in the open-access journal PLOS Genetics by a team at Cardiff University in the United Kingdom, led by Jeremy Guggenheim.
Bacterial biofilms can thrive on almost all types of surfaces: We find them on rocks and plants, on teeth and mucous membranes, but also on contact lenses, medical implants or catheters, in the hoses of the dairy industry or drinking water pipes, where they can pose a serious threat to human health.
In addition to antibodies and white blood cells, the immune system deploys peptides to fight viruses and other pathogens.
Infection, inflammation, trauma, disease, contact lenses - all of these and more can lead to corneal scarring, which according to the World Health Organization is a leading cause of blindness worldwide.
