Abstract
According to one embodiment, the disclosure provides a system for algal cell lysis. The system may include at least one algal cell, a plurality of metal nanoparticles, and an electromagnetic radiation generator. The generator may be able to generate radio frequency or microwave radiation that excites the plurality of metal nanoparticles, resulting in lysis of the algal cell. The disclosure also provides a system for recovery of a lipid from an algal cell similar to the above system but also including a separator. The disclosure further provides a method of recovering a lipid from an algal cell by supplying a plurality of metal nanoparticles to at least one algal cell, exciting the plurality of metal nanoparticles with radio frequency or microwave electromagnetic radiation, lysing the algal cell to release the lipid, and separating the lipid from the lysed algal cell.
