Bioceramics are important biomaterials in biomedical engineering because of their biocompatibility, bioactivity, osteoconductivity, and structural resemblance to actual bone tissue. In recent years, materials science and nanotechnology have enabled the use of bioceramics in bone regeneration, dental restoration, tissue engineering, drug delivery systems, and implantable medical devices. This comprehensive review covers advances in bioceramics, including calcium phosphates, hydroxyapatite (HAp), tricalcium phosphate, bioactive glasses, zirconia, alumina, and multifunctional ceramic nanocomposites. Priority is given to techniques such as additive manufacturing, 3D printing, sol-gel processing, electrospinning, and nanostructuring to improve mechanical strength, porosity, bioactivity, and cell interactions. Recent advances include ion doping, surface …
Shape Memory Alloy Capsule Micropump For Drug Delivery Applications, Youssef Mohamed Kotb
Shape Memory Alloy Capsule Micropump For Drug Delivery Applications, Youssef Mohamed Kotb
Theses and Dissertations
Implantable drug delivery devices have many benefits over traditional drug administration techniques and have attracted a lot of attention in recent years. By delivering the medication directly to the tissue, they enable the use of larger localized concentrations, enhancing the efficacy of the treatment. Passive-release drug delivery systems, one of the various ways to provide medication, are great inventions. However, they cannot dispense the medication on demand since they are nonprogrammable. Therefore, active actuators are more advantageous in delivery applications. Smart material actuators, however, have greatly increased in popularity for manufacturing wearable and implantable micropumps due to their high energy …
Synthesis, Characterization, And Application Of Chitosan Nanoparticles For In Vitro Studies On Hela Cancer Cells, Rejeena Jha
Synthesis, Characterization, And Application Of Chitosan Nanoparticles For In Vitro Studies On Hela Cancer Cells, Rejeena Jha
Graduate Theses/Dissertations
Chitosan is a fibrous substance that is derived from chitin, a natural substance in the shells of crustaceans. It possesses all the necessary qualities for being used as carrier for the transport of drugs and genes into tumor, such as biodegradability, biocompatibility, hydrophilicity, and non-toxicity and cationic in nature. Ionic gelation method was used to synthesize chitosan (CS) nanoparticles (NPs). Ionic gelation is a very benign process chemically that requires mixing a CS aqueous solution with a sodium tripolyphosphate (TPP) aqueous solution at room temperature. In addition, a surfactant polyethylene oxide (PEO) alone and a diblock copolymer of PEO and …
Electrospun Fibers With Smart Delivery Of Therapeutic Agents, Zahra Mahdieh
Electrospun Fibers With Smart Delivery Of Therapeutic Agents, Zahra Mahdieh
Graduate Student Theses, Dissertations, & Professional Papers
Electrospinning is the most widely studied technique of producing fibers. Delivery of nanoparticles and therapeutic agents from electrospun fibers have potential uses in various fields including drug delivery, filtration, and cosmetics. However, controlling the delivery rate remains the main challenge. In the current study, core-shell structure fibers were developed with zinc oxide nanoparticles applied in the shell composition to improve the pore structure (release pathway) and mechanical stability. Fine-tuned delivery rates were achieved via loading different sizes of silver nanoparticles (Ag NP) inside the fiber core. In vitro drug release assays showed fast, slow, and intermediate delivery rates of 20 …
Biomimetic Oral Mucin From Polymer Micelle Networks, Sundar Prasanth Authimoolam
Biomimetic Oral Mucin From Polymer Micelle Networks, Sundar Prasanth Authimoolam
Theses and Dissertations--Chemical and Materials Engineering
Mucin networks are formed by the complexation of bottlebrush-like mucin glycoprotein with other small molecule glycoproteins. These glycoproteins create nanoscale strands that then arrange into a nanoporous mesh. These networks play an important role in ensuring surface hydration, lubricity and barrier protection. In order to understand the functional behavior in mucin networks, it is important to decouple their chemical and physical effects responsible for generating the fundamental property-function relationship. To achieve this goal, we propose to develop a synthetic biomimetic mucin using a layer-by-layer (LBL) deposition approach. In this work, a hierarchical 3-dimensional structures resembling natural mucin networks was generated …
