Claim 1:
2. A method of synthesizing a siloxane derivative of the Formula I, comprising reacting a carboxyl end group of the following N-alkylated amino acid:, , with 3-aminopropyltris(trimethylsiloxy)silane to provide a siloxane derivative of the amino acid of the Formula I:, wherein R1 and R2 may be the same or different, and comprise at least one group selected from the group consisting of C1-C6 alkyl, optionally the C1-C6 alkyl may include one or more of oxygen, nitrogen, or sulfur atoms or groups that include at least one of these atoms, and the alkyl chain may be optionally substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
n is an integer from 3 to 12;
the terminal nitrogen is optionally further substituted with R3, wherein R3 is selected from the group consisting of hydrogen, oxygen, hydroxyl, and C1-C6 alkyl; and
an optional counterion associated with the compound which, if present, is selected from the group consisting of chloride, bromide, and iodide.
