Abstract

Materials for targeted drug delivery and gene transfer, in particular for DNA and siRNA delivery into cells, are currently the two most relevant in the international pharmacological market. The leading positions in the field of drug delivery belong to the biocompatible and biodegradable multifunctional nanoscale materials capable of forming water-soluble forms of drugs, providing their addressed delivery, and crossing the biological barriers in the organism. Labeling these materials with a biocompatible dye is also important for monitoring drug action or gene expression, biodistribution, and excretion from the treated organism.

In this chapter, principal approaches used in the synthesis of materials for gene delivery are shown, and their biocompatibility and functions are characterized for cells of different origin, namely, bacteria, yeast, plants, and mammals. Usually, the DNA that should be delivered to the target cells is “labeled” by gene coding for the green fluorescent protein (GFP); the gene delivery platform might be additionally labeled with a specific fluorescent dye. This helps monitoring the uptake, biodistribution, and location of the action of the transported nucleic acid in the cell (tissue, organ, organism), as well as the ways of possible clearance of the gene delivery platform from the body.

The chemical structure of materials for delivery of nucleic acids used in gene therapy should contain a positively charged group, usually an amine. Some advanced platforms also contain covalently conjugated vector elements (e.g., antibody or other ligand for specific receptors on plasma membrane of the targeted cells) for the addressed action. The hybrid platforms for simultaneous delivery of anticancer drugs and specific siRNA were created, and such multifunctionality is an important trend in the development of novel nanoscale materials used for disease treatment, gene therapy, and other biomedical purposes.
