Novel methods and devices which provide enhanced mixing, and application of two liquid components to form a biomaterial with minimized aerosols, are achieved using airflow rates below about 1.25 liters/minute in combination with a ratio of airflow to total liquid flow of from about 150:1 up to about 1500:1. Preferably the airflow is below abou t 1 liter/minute, and the ratio of airflow to total liquid flow is from about 200:1 to about 1200:1. The parameters are ideally suited for the spray application of components which form a surgical sealant, e.g., a fibrin sealant. Also a part of the present invention is novel application methods for biomaterial, e.g., surgical sealant, components at liquid flows below 1.9 ml/minute, novel methods involving the mixing of such components on the exit surface of a spray tip (14), or nozzle, novel spray tips (14), biomaterial applicators, and methods for maki ng such applicators.
