Poly(lactic-co-glycolic acid) (PLGA) Nanoparticles for Drug Delivery is a comprehensive guide to PLGA nanoparticles for targeting various diseases, covering principles, formation, characterization, applications, regulations and the latest advances. Sections introduce the fundamental aspects of PLGA nanoparticles for drug delivery, including properties, preparation methods, characterization, drug loading methods, and drug release mechanisms, along with a focus on applications. Application of PLGA nanoparticles for the treatment of cancer, inflammatory, cerebral, cardiovascular, and infectious diseases, as well as in regenerative medicine, photodynamic and photothermal therapy, and gene therapy, are all explained in detail. The final chapters explore recent advances and regulatory aspects. This book is a valuable resource for researchers and advanced students across nanomedicine, polymer science, bio-based materials, chemistry, biomedicine, biotechnology, and materials engineering, as well as for industrial scientists and R&D professionals with an interest in nanoparticles for drug delivery, pharmaceutical formulations and regulations, and development of innovative biodegradable materials.
This book is the third volume on this subject and focuses on the recent advances of nanopharmaceuticals in cancer, dental, dermal and drug delivery applications and presents their safety, toxicity and therapeutic efficacy. The book also includes the transport phenomenon of nanomaterials and important pathways for drug delivery applications. It goes on to explain the toxicity of nanoparticles to different physiological systems and methods used to assess this for different organ systems using examples of in vivo systems.
Traumatic brain injury (TBI) presents a serious challenge for modern medicine due to the poor regenerative capabilities of the brain, complex pathophysiology, and lack of effective treatment for TBI to date. The overall goal of this research is to develop as nanoparticle capable of sustained drug release for the delivery and treatment of TBI so that therapeutic drug can be delivered after the Blood Brain Barrier (BBB) closes 24 hours after injury. Poly(lactic-co-glycolic acid) (PLGA) nanoparticles have shown some experimental success; as of yet, none have yielded improved results of clinical efficacy. Polyethylene Glycol (PEG) has been shown to act as a stealth molecule that can increase the circulation time of particles. N-acetylcysteine has shown neuroprotective and anti-inflammatory potential. This paper presents the development of PEGylated PLGA NPs synthesized using double and single emulsion for potential therapeutic delivery to TBI. Dynamic light scattering (DLS) show PEG-PLGA NPs to have an average diameter of 200 nm. Loading capacity was obtained at 2%, and drug encapsulation efficiency was obtained at 55%. A biphasic drug release pattern was noted in situ and drug release was assessed in vitro over 72 h using FRET nanoparticles, almost complete release of drug was seen during this time period. Finally, in vivo administration of PEG-PLGA NPs demonstrated that PEGylated NPS were able to show reduced accumulation in filtration organs such as the liver and kidneys compared to bare PLGA particles. This evidence supports the potential of PEG-PLGA NPs as a promising carrier to develop TBI therapeutics.

Seaweed Polysaccharides: Isolation, Biological, and Biomedical Applications examines the isolation and characterization of algal biopolymers, including a range of new biological and biomedical applications. In recent years, significant developments have been made in algae-based polymers (commonly called polysaccharides), and in biomedical applications such as drug delivery, wound dressings, and tissue engineering. Demand for algae-based polymers is increasing and represent a potential—very inexpensive—resource for these applications. The structure and chemical modification of algal polymers are covered, as well as the biological properties of these materials – including antithrombic, anti-inflammatory, anticoagulant, and antiviral aspects. Toxicity of algal biopolymers is also covered. Finally, the book introduces and explains real world applications of algal-based biopolymers in biomedical applications, including tissue engineering, drug delivery, and biosensors. This is the first book to cover the extraction techniques, biomedical applications, and the economic perspective of seaweed polysaccharides. It is an essential text for researchers and industry professionals looking to work with this renewable resource. Provides comprehensive coverage of the research currently taking place in biomedical applications of algae biopolymers Includes practical guidance on the isolation, extraction, and characterization of polysaccharides from sustainable marine sources Covers the extraction techniques, biomedical applications, and economic outlook of seaweed polysaccharides
This volume serves as a valuable handbook for the development of nanomedicines made of polymer nanoparticles because it provides researchers, students, and entrepreneurs with all the material necessary to begin their own projects in this field. Readers will find protocols to prepare polymer nanoparticles using different methods, since these are based on the variety of experiences that experts encounter in the field. In addition, complex topics such as, the optimal characterization of polymer nanoparticles is discussed, as well as practical guidelines on how to formulate polymer nanoparticles into nanomedicines, and how to modify the properties of nanoparticles to give them the different functionalities required to become an efficient nanomedicine for different clinical applications. The book also discusses the translation of technology from research to practice, considering aspects related to industrialization of preparation and aspects of regulatory and clinical development.
Many times drugs work fine when tested outside the body, but when they are tested in the body they fail. One of the major reasons a drug fails is that it cannot be absorb by the body in a way to have the effect it was intended to have. Permeability, Solubility, Dissolution, and Charged State of Ionizable Molecules: Helps drug discovery professionals to eliminate poorly absorbable molecules early in the drug discovery process, which can save drug companies millions of dollars. Extensive tabulations, in appendix format, of properties and structures of about 200 standard drug molecules.
Emphasizing four major classes of polymers for drug delivery-water-soluble polymers, hydrogels, biodegradable polymers, and polymer assemblies-this reference surveys efforts to adapt, modify, and tailor polymers for challenging molecules such as poorly water-soluble compounds, peptides/proteins, and plasmid DNA.
