Abstract
The introduction of tools to study, control or expand the inner-workings of algae has been slow to develop. Provided are embodiments of a molecular method based on guanidinium-rich molecular transporters (GR-MoTrs) for bringing molecular cargos into algal cells. The methods of the disclosure have been shown to work in wild-type algae that have an intact cell wall. Developed using Chlamydomonas reinhardtii, this method is also successful with less studied algae, including Neochloris oleoabundans and Scenedesmus dimorphus, thus providing a new and versatile tool for algal research and modification. The method of delivering a cargo compound to an algal cell comprises contacting an algal cell with a guanidinium-rich delivery vehicle comprising a guanidinium-rich molecular transporter (GR-MoTr) linked to a cargo compound desired to be delivered to the algal cell, whereby the guanidinium-rich molecular transporter can traverse the algal cell wall, thereby delivering the cargo compound to the algal cell.
