Formulation of three tailed bacteriophages by spray-drying and atomic layer deposition for thermal stability and controlled release.

Deep infection is the second most common complication of arthroplasty following loosening of the implant. Antibiotic-loaded bone cements (ALBCs) and high concentrations of systemic broad-spectrum antibiotics are commonly used to prevent infections following injury and surgery. However, clinical data fails to show that ALBCs are effective against deep infection, and negative side effects can result following prolonged administration of antibiotics.

Stabilization of an Infectious Enveloped Virus by Spray-Drying and Lyophilization.

Enveloped viruses are attractive candidates for use as gene- and immunotherapeutic agents due to their efficacy at infecting host cells and delivering genetic information. They have also been used in vaccines as potent antigens to generate strong immune responses, often requiring fewer doses than other vaccine platforms as well as eliminating the need for adjuvants. However, virus instability in liquid formulations may limit their shelf life and require that these products be transported and stored under stringently controlled temperature conditions, contributing to high cost and limiting patient access.
