We derive, for spacetimes admitting a Spin(7) structure, the general local bosonic solution of the Killing spinor equation of 11-dimensional supergravity. The metric, four-form, and Killing spinors are determined explicitly, up to an arbitrary eight-manifold of Spin(7) holonomy. It is sufficient to impose the Bianchi identity and one particular component of the four-form field equation to ensure that the solution of the Killing spinor equation also satisfies all the field equations, and we give these conditions explicitly.

Background: Surgical site infections (SSIs) have been shown to increase patient morbidity and mortality, impact on quality of life and place a significant economic burden on healthcare systems worldwide. Irrigation using wound cleansing and antiseptic effective solutions during surgical procedures is a key part of SSI prevention. The optimal solution would have minimal cytotoxicity to the patient while maintaining a minimum concentration required for antimicrobial activity necessary to prevent opportunistic pathogens and biofilm formation.

The predominant adverse health effects in care delivery result from hospital-acquired (nosocomial) infections, which impose a substantial financial burden on global healthcare systems. Integrating contact-killing antibacterial action, gas permeability, and antioxidant properties into textile coatings offers a transformative solution, significantly enhancing both medical and everyday protective applications. This study presents an innovative, pollution-free physical compounding method for creating a fluorescent biopolymer composite embedded with silicene-based heteroatom-doped carbon quantum dots for the production of functional textiles.
