“…The outer layer of liquid ('thin') albumen surrounds a bag of mucilaginous ('thick') albumen which itself contains an inner layer of thin albumen. The three layers may readily be separated in a fresh egg (see Methods), and it has been shown that when they are compared with respect to refractive index and specific content of solid matter* (Romanoff & Sullivan, 1937) and density (Frampton & Romanoff, 1947), each of these measurements rises as one proceeds inwards from the outer thin via the thick to the inner thin.…”

The genetics of two polymorphic loci in the fowl was studied. Each affects the electrophoretic mobility of a different egg albumen protein, and at each locus two alleles were shown to segregate in a Mendelian manner.The polymorphic proteins are not any of the well-characterized egg albumen proteins, viz. ovalbumin, ovomucoid, ovomucin, flavoprotein, avidin and lysozyme.In contrast to all others, two hens were found to have an anomalous, variable, phenotype. A tentative explanation of this was offered.

“…Furthermore, ovalbumin, the main protein of EW, has a high refractive index, about 1.55 at 600 nm [20], which is higher than that of PVA (around 1.45) [12] and starch polymer (1.53) [21]. As a result, EW can have a high refractive index which is crucial for making high-quality (Q) factor cavities [20,22].…”

Biolasers made of biological materials hold great potential for implantable biosensing and cell-tracking. However, the current bio-extracted materials used for biolasers generally require a complicated synthesis process and therefore suffer from high cost. In this work, we demonstrate that low-cost natural egg white is an excellent biomaterial for a laser cavity. Using a simple dehydration method, dye-doped goose egg white microspheres are obtained with various sizes from 20 to 160 µm in diameter. These microspheres can act as excellent laser sources under optical excitation with lasing threshold of ∼26 µJ mm−2 and quality (Q) factor up to 3 × 103. The lasing mechanism is studied and ascribed to the whispering gallery mode. Size-dependence of the lasing spectrum and Q factor are also investigated. Owing to the ease of fabrication, the cost-effectiveness, goose egg white based microlasers are promising for biosensing and bioimaging applications.
