👉 In physics, an antispreader is a material that can resist the movement of electrons. It is often used in electronics to prevent the movement of electrons through a circuit or component. For example, in a diode, antispreaders are used to prevent the flow of current when the diode is being discharged. The term "antispreader" was introduced into physics by physicist Alexander Fleming who discovered that antifungals (antibacterial drugs) can inhibit the growth of bacteria and
