Regular nanometer-scale patterning down to a few tens of nanometers and the manufacturing diffractive optical elements in silk by using ideas soft lithography is reported. The unique processing films makes them an ideal substrate incorporate biological matter (such as small organics, enzymes, proteins, cells). Unprecedented definition transverse direction, with features nanometers,

We demonstrate controllable structural color based on periodic nanopatterned 2D lattices in pure protein films of silk fibroin. show here fibroin with feature sizes hundreds nanometers that exhibit different colors as a function varying lattice spacing. Further, when the index refraction contrast between and its surrounding environment by applying liquids top lattices, colorimetric shifts are observed. The effect is characterized experimentally theoretically simple example glucose...

Free-standing silk films are useful materials to manufacture nanopatterned optical elements and immobilize bio-dopants such as enzymes while maintaining their biological activity. These traits were combined by incorporating hemoglobin into free-standing diffraction gratings fabricate chemically responsive optofluidic devices ambient gas conditions, constituting a simple oxygen sensor. This type of self-analyzing system is enabled the unique ability reproduce high-fidelity structures in...

Background It is unclear whether breast US screening outcomes for women with dense breasts vary levels of cancer risk. Purpose To evaluate female patients and different estimated risk levels. Materials Methods This retrospective observational study used data from examinations in heterogeneously or extremely conducted January 2014 to October 2020 at 24 radiology facilities within three Breast Cancer Surveillance Consortium (BCSC) registries. The primary were the detection rate, false-positive...

Abstract Background There are no consensus guidelines for supplemental breast cancer screening with whole‐breast ultrasound. However, criteria women at high risk of mammography failures (interval invasive or advanced cancer) have been identified. Mammography failure was evaluated among undergoing ultrasound in clinical practice compared alone. Methods A total 38,166 ultrasounds and 825,360 mammograms without were identified during 2014–2020 within three Breast Cancer Surveillance Consortium...
