Methods and compositions for serum-stabilizing micelles for drug delivery or imaging agent delivery are provided, as well as methods and compositions to enhance micelle-mediated drug delivery. This invention provides a process for synthesizing a lipid micelle comprising one or more lipid-oligonucleotide conjugate molecules, the process comprising contacting an amount of lipid molecules with an amount of lipid-oligonucleotide conjugate molecules sufficient to create a lipid micelle comprising lipid-oligonucleotide conjugate molecules.
