2. 1. Nanocellulose based 3D printed hydrogel scaffolds for cartilage and bone regeneration : Tuning of composition, pore structure and functions

   Author : Sahar Sultan; Aji P. Mathew; Lennart Bergström; Gustav Nyström; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocellulose materials; 3D printing; gradient biphasic hydrogel scaffolds; metal-organic frameworks; hydroxyapatite; cartilage and bone regeneration; osteochondral scaffolds; materialkemi; Materials Chemistry;

   Abstract : Biobased-materials with customized scaffolds have played a prominent role in the success of tissue engineering (TE). Cellulose nanomaterials (CNM) isolated from the abundant biopolymer, cellulose, is explored in this thesis for TE engineering due to its versatile properties such as biocompatibility, high specific strength, surface functionality and water retention capacity.

4. 2. Hyaluronan Derivatives and Injectable Gels for Tissue Engineering

   Author : Kristoffer Bergman; Tim Bowden; Jöns Hilborn; Jeffrey Hubbell; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hyaluronan; Hydrogel; Tissue Engineering; Scaffold; Minimally invasive strategy; Bone morphogenetic protein; Hydroxyapatite; Bone; Cartilage; Tendon; Polymer chemistry; Polymerkemi;

   Abstract : The present work describes the preparation of hyaluronan derivatives and hydrogels with potential use in tissue engineering applications. A potentially injectable hydrogel consisting of hyaluronan and collagen was successfully used to grow neurons in vitro by encapsulation of neural stem and progenitor cells. READ MORE

5. 3. Ceramic Materials as Drug Delivery Systems

   Author : Amina Vazda; Håkan Engqvist; Santos Hélder; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drug delivery; ceramics; Abuse deterrent; inhalation; single-crystals;

   Abstract : The aim of this thesis is to evaluate ceramic materials for drug delivery drugs applications. Three delivery routes were investigated; abuse-deterrent oral formulation, inhalation, and novel ceramic crystals with drug entrapped. A geopolymer matrix was developed in order to withstand non-medical abuse such as crushing, snorting, extraction etc. READ MORE
