Liquid Crystalline Networks Hamper the Malignancy of Cancer Cells

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Liquid Crystalline Networks are used as scaffolds for the growth of A375 melanoma cells demonstrating to affect their malignancy. Indeed, only by contact, these materials reduces cell proliferation and colony formation capacity, while increasing the number of senescent cells and promoting the mesenchymal to epithelial transition.

Observations on Scanning Electron Microscopy of Hydrophilic Contact Lenses [PDF]

Clinical and Experimental Optometry, 1974
Hydrated hydrophilic lenses, Bionite and Hydron, were prepared for scanning electron microscopy by air drying and freeze drying techniques. Air dried lenses shrank more on dehydration (with more distortion to overall lens shape) than freeze dried lenses.

Adherence of Pseudomonas aeruginosa to hydrophilic contact lenses and other substrata [PDF]

Journal of Clinical Microbiology, 1987
Nonmucoid Pseudomonas aeruginosa isolated from corneal ulcers and contact lens cases and solutions were examined for their ability to adhere to polystyrene, glass, and hydrophilic contact lenses of varying water content and polymer composition. Adherence to the various substrates was strain specific.
