In this paper, an egg-shell membrane has been used for efficient immobilization and stabilization of glucose oxidase. This membrane was used for developing a simple and reusable method for estimation of glucose in biological samples. The proposed sensor was effectively used in a wide glucose concentration range (1 - 1000 mM) with fast response time of 70 s for higher concentrations and 120 s for lower concentrations. The results of response study for the fabricated sensor show limit of detection of 4.761 mM with high sensitivity over the entire concentration range (1 - 1000 mM). Most interestingly, the membrane used in the fabricated sensor could be repeatedly used for glucose analysis 150 times and it exhibited a shelf-life of more than 6 weeks. The proposed sensor was also demonstrated for estimation of glucose in human blood samples.

Chronic diabetic wounds pose significant clinical challenges due to persistent inflammation, impaired neovascularization, and recurrent infections. This study is based on the natural three-dimensional porous structure and bioactive components of eggshell membranes (ESM), on which we assembled an in situ Cu@MOF, richly loaded with Cu and Zn, to create a multifunctional wound dressing (ESM@Cu-MOF). The characterization results demonstrated that the ESM@Cu-MOF exhibited excellent antibacterial performance and cell compatibility, with pH-responsive ion release characteristics.

Valued for their nutritional content, eggs have recently gained attention as a versatile biomaterial owing to their biocompatibility, biodegradability, and unique structural and biochemical composition. This review highlights the biomedical potential of various egg components-eggshell, eggshell membrane, egg white, and egg yolk-and their applications in bone grafting, tissue engineering, wound healing, drug delivery, and biosensors. Eggshells serve as a natural, calcium-rich source for bone tissue engineering and regenerative medicine.

Background: The eggshell membrane (ESM) is a natural resource with a distinct design and composition, offering structural features consistent with barrier membranes used in guided bone regeneration (GBR), making it a promising candidate for this application. This study aims to assess the feasibility of chicken and duck ESMs as GBR alternatives by comparing them with resorbable porcine-derived collagen (Porcine CM, Bio-Gide®) and non-resorbable dense polytetrafluoroethylene (d-PTFE, Cytoplast).
Methods: ESMs were extracted using a standardized protocol.

Eggshell membrane (ESM), a protein-rich byproduct of the egg processing industry, contains latent bioactive sequences with physiological relevance, but remains largely underutilized. To evaluate its potential as a novel source of dipeptidyl peptidase-IV (DPP-IV) inhibitory peptides, ESM was enzymatically hydrolyzed using five proteases, among which alkaline proteases exhibited the most effective hydrolysis. The resulting hydrolysates were systematically assessed for DPP-IV inhibitory activity, amino acid composition, and peptide sequence characteristics.

The periosteum is a highly vascularized tissue and possesses exceptional osteogenic and bone regenerative capabilities. These properties make it an important component in bone defect repair. This study introduced a newly developed, polyethyleneimine-enhanced eggshell membrane (PESM) designed to promote dual regeneration of bone and periosteum.
