What are lipid nanoparticles? How are they structured? How are they formed? What techniques are best to characterize them? How great is their potential as drug delivery systems? These questions and more are answered in this comprehensive and highly readable work on lipid nanoparticles. This work sets out to provide the reader with a clear and understandable understanding of the current practices in formulation, characterization and drug delivery of lipid nanoparticles. A comprehensive description of the current understanding of synthesis, characterization, stability optimization and drug incorporation of solid lipid nanoparticles is provided. Nanoparticles have attracted great interest over the past few decades with almost exponential growth in their research and application. Their small particle size and subsequent high surface area make them ideal in many uses, but particularly as drug carrier systems. Nanoparticles made from lipids are especially attractive because of their enhanced biocompatibility imparted by the lipid. The work provides a detailed description of the types of lipid nanoparticles available (e.g. SLN, NLC, LDC, PLN) and how they range from imperfect crystalline to amorphous in structure. Current thoughts on where drugs are situated (e.g. in the core, or at the interface) and how this can be manipulated are discussed. The many techniques for production, including the author’s own variant of microwave heating, are fully discussed. Techniques for measuring arguably the most important characteristics of particle size and polydispersity are discussed, along with techniques to measure crystallinity, shape and drug capacity. Finally, a full chapter on techniques for measuring stability, both in the absence and presence of drugs, is discussed, along with suggestions on how to optimize that stability. This work appeals to students of colloid science, practitioners of research into drug delivery and academics alike.

Solid lipid-polymer hybrid nanoparticles (SLPN) are nanocarriers made from a combination of polymers and lipids. By integrating the advantages of biocompatible lipid-based nanoparticles and gastrointestinal (GI)-stable polymeric nanoparticles, SLPN are the ideal delivery system for delivering lipophilic compounds orally. In this project, two novel preparation strategies were proposed to fabricate GI-stable SLPN: 1) Bovine serum albumin (BSA) and dextran were first conjugated through Maillard reaction and the conjugates were exploited as macromolecular emulsifier and surface coating layer to prepare SLPN by a solvent diffusion and sonication method. In this approach, the multilayer structure was formed by self-assembly of BSA-dextran micelles to envelope solid lipid via a pH- and heating-induced facile process with simultaneous surface deposition of pectin; 2) Dextran was first oxidized and functionalized with more surface aldehyde groups, and then the SLPN was fabricated through in situ conjugation between oxidized dextran and BSA-emulsified solid lipid. Both types of SLPN were applied to encapsulate lipophilic bioactive compounds, including curcumin and astaxanthin (ASTN). The major objectives of this dissertation were to 1) systematically study the fabrication parameters in two preparation strategies to prepare SLPN; 2) comprehensively characterize the structural and colloidal properties of as-prepared two types of SLPN; 3) explore and compare the encapsulation and delivery applications of SLPN for lipophilic bioactive compounds, including curcumin and ASTN. In summary, the surface-functionalized SLPN could significantly improve the physicochemical properties of lipid nanoparticles and expand their potential as oral delivery systems for lipophilic bioactive compounds.

This book features a special subsection of Nanomedicine, an application of nanotechnology to achieve breakthroughs in healthcare. It exploits the improved and often novel physical, chemical and biological properties of materials only existent at the nanometer scale. As a consequence of small scale, nanosystems in most cases are efficiently uptaken by cells and appear to act at the intracellular level. Nanotechnology has the potential to improve diagnosis, treatment and follow-up of diseases, and includes targeted drug delivery and regenerative medicine; it creates new tools and methods that impact significantly upon existing conservative practices. This volume is a collection of authoritative reviews. In the introductory section we define the field (intracellular delivery). Then, the fundamental routes of nanodelivery devices, cellular uptake, types of delivery devices, particularly in terms of localized cellular delivery, both for small drug molecules, macromolecular drugs and genes; at the academic and applied levels, are covered. The following section is dedicated to enhancing delivery via special targeting motifs followed by the introduction of different types of intracellular nanodelivery devices (e.g. a brief description of their chemistry) and ways of producing these different devices. Finally, we put special emphasis on particular disease states and on other biomedical applications, whilst diagnostic and sensing issues are also included. Intracellular delivery / therapy is a highly topical which will stir great interest. Intracellular delivery enables much more efficient drug delivery since the impact (on different organelles and sites) is intracellular as the drug is not supplied externally within the blood stream. There is great potential for targeted delivery with improved localized delivery and efficacy.
