He invented the surgical suture "Equiestene". He did research in a wide variety of areas: physico-chemical, electrochemical, and physiological aspects; specific heats and latent heats of vaporization; specific induction capacities; separation of lithium from alkalies; vapor tension; osmosis; equilibria; hydrolysis of cellulose; new solvents for cellulose, sulphur and keratin; sulphur content of keratin; single potential of aluminum and arsenic; the electrochemical series of the metals; separation of crystalloids from one another by dialysis; colloids; passage of boric acid and other compounds through the skin and other living membranes; catalytic hydrogenation of oils; cholesterin; colloidal gold in cases of malignancy; qualitative analysis; and chemistry in daily life.
