A novel type of supramolecular aggregate, named "nanosponge" was synthesized through the interaction of novel supramolecular building blocks with trigonal geometry. The cholesterol-(K/D)[subscript n]DEVDGC)3-trimaleimide unit consists of a trigonal maleimide linker to which homopeptides (either K or D) of variable lengths (n = 5, 10, 15, 20) and a consensus sequence for executioner caspases (DEVDGC) are added via Michael addition. Upon mixing in aqueous buffer, cholesterol-(K)[subscript n]DEVDGC)3-trimaleimides, as well as a 1:1 mixture of cholesterol-(K/D)[subscript n]DEVDGC)3-trimaleimides form stable nanosponges, whereas cholesterol-(D)[subscript n]DEVDGC)3-trimaleimide is unable to form supramolecular aggregates by itself. The structure of the novel nanosponges was revealed through explicit solvent and then coarse-grained molecular dynamics (MD) simulations. The nanosponges are between 80nm and several micrometers in diameters and virtually non-toxic to monocyte/macrophage-like cells. Furthermore, the structure of novel binary nanosponges consisting of cholesterol-(K/D)[subscript n]DEVDGC)3-trimaleimide units possessing a trigonal maleimide linker, to which either lysine (K)20 or aspartic acid (D)20 are tethered, has been elucidated by means of TEM. A high degree of agreement between these findings and structure predictions through explicit solvent and then coarse-grained molecular dynamics (MD) simulations has been found. Based on the nanosponges' structure and dynamics, caspase-6 mediated release of the model drug 5(6)-carboxyfluorescein has been demonstrated. Moreover, the binary (DK20) nanosponges have been found virtually non-toxic in cultures of neural progenitor cells. Additionally, DK20 nanosponges were taken up efficiently by leucocytes (WBC) in peripheral blood within 3h of exposure. The percentage of live cells among the WBC was not significantly decreased by the DK20 nanosponges. Therefore, this novel material holds great promise for improved cell-mediated therapy. Two different nanosponges loaded with the anticancer agent perillyl alcohol (POH) were developed to test the suitability of nanosponges for cell-based cancer therapy. Drug-loaded nanoshuttles featuring trigonal supramolecular building blocks, type (D-POH)10K20 and (D-POH)10R20 were synthesized, purified, and characterized by Dynamic Light Scattering (DLS) and Atomic Force Microscopy (AFM). They were then tested in cell cultures of murine glioma cells (GL26) and murine neural progenitor cells (NPC). The two nanosponges exhibited significantly different biophysical properties (size distribution and zeta potentials). Consequently, different efficacies in killing GL26 and NPC were observed in both, serum free and serum containing culture media. The results from these experiments confirmed that type (D-POH)10K20 nanosponge is an excellent candidate for the cytotherapy of glioblastoma.

This book provides an overview of various drug delivery systems at the cellular level including biological, chemical methods, and most importantly physical methods such as photoporation, electroporation, mechanoporation, and device-based techniques (e.g., microfluidics), as well as organism-level techniques including nanomaterials, biomaterials, and transdermal. Drug delivery (DD) can be defined as the method and route by which an active pharmaceutical ingredient (API) is administered to promote its desired pharmacological effect and/or convenience and/or to reduce adverse effects. Drug delivery systems are developed to maximize drug efficacy and minimize side effects. As drug delivery technologies improve, the drug becomes safer and more comfortable for patients to use. During the last seven decades, extraordinary progress has been made in drug delivery technologies, such as systems for long-term delivery for months and years, localized delivery, and targeted delivery. The advances, however, will face the next phase considering the future technologies that we need to overcome many physicochemical barriers for new formulation development and biological unknowns for treating various diseases. Thus, various technologies are built at a single-cell level as well as an organism level. This book is useful at the university level for graduate courses or research studies and biotechnology-based companies with research and development on cell-based analysis, diagnosis, or drug screening. This book is also very useful for researchers in drug delivery technologies, which came in frontier research for the past decade.

Nanotechnology showed great promise and impact on administration of therapeutic agents owing to its advantages over contemporary delivery systems. Nanoscale carriers like nanosponges represent a novel category of hyper cross-linked polymer structures with nanosized cavities which can be filled with variety of active moieties (hydrophilic as well as hydrophobic). These nanocarriers can circulate around the body until they found the specific target site and adhere on the surface and release the active moiety in a predictable and controlled manner, resulting in more effective delivery of a given dosage. Nanosponge technology helps to reduce drug associated side effects, improve stability, increase elegance and improve the flexibility of formulations, administered orally, parenterally and topically. Among nanosponges, cyclodextrin-based nanosponges (CDNS) are smart versatile carriers studied widely for drug delivery applications. Statistically, it have presented that approximately 40% of active moieties marketed currently and about 90% of active moieties in their preliminary phase confront problems regarding to solubility. In the past decade, the number of studies describing CDNS has dramatically increased. In the present chapter, scientists working in arena of nanotechnology can get an idea of fabrication, characterization and therapeutic utilities of nanosponges.
