The present invention relates to the design and development of a drug delivery nanoplatform that consists of nanoporous, multi-layer biodegradable polymeric (BP) thin films for controlled release of its payload. The method is used notably to synthesize nanoporous BP coatings as drug delivery vehicles exhibiting uniform nanopores with tailored characteristics for control of drug delivery and release. It enables the multiplex delivery of drugs that can be eluted at desirable time intervals in line with each medical need. Atomic Force Microscopy and Spectroscopic Ellipsometry are applied for determining nanoporosity, thickness, drug loading, structural properties, and quality of the BP films ensuring the quality control of the final product. The complete degradation of the polymers minimizes the toxicity within the human body and such nanoplatform can be used in a wide range of drug eluting and other medical implants and biomedical devices.
