Our ability to precisely manipulate size, shape, and composition of nanoscale carriers is essential for controlling their in-vivo transport, biodistribution, and drug release mechanism. Shape-specific, "smart" nanoparticles that deliver drugs or imaging agents to target tissues primarily in response to disease-specific or physiological signals could significantly improve therapeutic care of complex diseases. Current methods in nanoparticle synthesis do not allow such simultaneous control over particle size, shape, and environmentally-triggered drug release, especially at the sub-100 nm range. In this dissertation, we discuss the development of high-throughput nanofabrication techniques using synthetic and biological macromers (peptides) to produce highly monodisperse nanoparticles, as well as enzymatically-triggered nanoparticles, of precise sizes and shapes. We evaluated thermal nanoimprint lithography (ThNIL) and step and flash imprint lithography (SFIL) as two possible fabrication techniques. We successfully employed ThNIL and SFIL for fabricating nanoparticles and have extensively characterized the SFIL fabrication process, as well as the properties of the imprinted biopolymers. Particles as small as 50 nm were fabricated on silicon wafers and harvested directly into aqueous buffer using a biocompatible, one-step release technique. These methods provide a novel way to fabricate biocompatible nanoparticles with precise size and geometry. Furthermore, we developed an enzyme-degradable material system and demonstrated successful encapsulation and enzyme-triggered release of antibodies and nucleic acids from these imprinted nanoparticles; thus providing a potential means for disease-controlled delivery of biomolecules. Finally, we evaluated the bioactivity of the encapsulated therapeutics in-vitro. The development of the SFIL method for fabrication of biocompatible nanocarriers has great potential in the drug delivery field for its ability to create monodisperse particles of pre-designed geometry and size, and to incorporate stimulus-responsive release mechanisms. This research provides the potential to broaden the study of how particle size and shape affect the biodistribution of drugs within the body.

The advent of highly sophisticated drugs designed to interfere with specific cellular functions has created the demand for "intelligent" carriers that can efficiently deliver therapeutic agents in response to a pathophysiogical condition. Nanoscale intelligent systems can maximize the efficacy of therapeutic treatments in numerous ways because they have the ability to rapidly detect and response to disease states directly at the site and sparing physiologically healthy cells and tissues, thereby improving a patient's quality of life. Nanoparticle fabrication has primarily relied on emulsions, self-assembly and micelles based methods which inherently generate polydisperse spherical particles with little control over particle geometry. Despite significant progress in such drug delivery systems, critical limitations remain in synthesizing nanocarriers with highly controllable architecture (size, shape or aspect ratio) that can, at the same time, impart response-sensitive release mechanisms. These parameters are essential for controlling the in-vivo transport, bio-distribution, and drug release mechanisms. The objective of my dissertation is to employ the nanofabrication technique Step and Flash Imprint Lithography (S-FIL) to synthesize stimuli-responsive nanocarriers of precise architectures and composition. Applying S-FIL technology, fabrication of nanocarriers of a variety of shapes and sizes (down to 36nm length scale) that are also environmentally responsive by incorporating enzymatically-degradable peptides into the nanocarrier hydrogel matrix, to provide triggered release of encapsulated therapeutic agents in response to specific pathophysiological conditions, has been accomplished. Besides disease-responsive release, the two key properties of an effective nanocarrier are (a) efficient targeting to specific tissues and cells and (b) avoiding rapid clearance and remaining in circulation in the blood stream for a significant amount of time to increase particle uptake in target tissues. These two properties are expected to be dependent on the shape and size of the carriers. Using various shape and size S-FIL fabricated nanoparticles, the effects of particle geometry on intracellular uptake has also been evaluated. In this dissertation, I will present the extensive work that has been done in the fabrication and optimization of the S-FIL nanocarriers, evaluation of the nanocarrier's in vitro properties, and evaluation of the effects of nanocarrier geometry on intracellular uptake.
