Mesoporous Bioactive Glasses: A Powerful Tool in Tissue Engineering and Drug Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This work is a comprehensive revision of bioactive glasses (BGs), pioneered by Prof. L.L. Hench, which are key in bone repair and regenerative medicine. Sol–gel methods and mesoporous designs enhanced their bioactivity, ions, and drug delivery. BGs now support gene therapy and 3D‐printed scaffolds, enabling personalized, multifunctional treatments in ...

Visible Light Induced DLP‐Printed Oxygen‐Releasing TPMS Scaffolds Mitigate Early Hypoxia in Bone Defects

open access: yesAdvanced Healthcare Materials, EarlyView.
Visible light‐induced digital light processing 3D printed Primitive‐triply periodic minimal surface hydrogels embed CaO2–Si core–shell nanoparticles to deliver short‐term oxygen during the avascular window. The scaffolds maintain cytocompatibility, elevate osteopontin in vitro, and enhance calvarial defect repair in vivo without toxicity.

Pengaruh Penambahan Surfaktan pada Sintesis Zeolit Y Menggunakan Tetraethyl Orthosilicate (TEOS) sebagai Sumber Silika

open access: yesJurnal Kimia Sains dan Aplikasi, 2011
Zeolit alam mempunyai ukuran pori yang beragam antara 3 Å hingga 8 Å, sehingga tidak efektif untuk mengadsorpsi senyawa yang berukuran besar. Zeolit sintetik (zeolit Y) dikembangkan untuk mengatasi kelemahan dari zeolit alam.

Thiolated Hyaluronic Acid: A Gateway for Targeted Killing of Staphylococcus aureus on the Race for Surface Colonization

open access: yesAdvanced Healthcare Materials, EarlyView.
Thiolated hyaluronic acid (HAMS) synthesized and characterized by NMR, solubility, thiol content, and pKa, is degraded by Staphylococcal hyaluronate lyase but not by mammalian hyaluronidase. Coating polyphosphate–M23 phage endolysin nanoparticles (M23‐PP) with HAMS confers Staphylococcus aureus responsiveness.

Metronidazole‐Loaded Cyclodextrin Nanogels for Antibacterial Therapy and Microbiota Regulation in Periodontitis

open access: yesAdvanced Healthcare Materials, EarlyView.
A methacrylamide β‐cyclodextrin‐based nanogel (MACD nGel) is developed to load the antimicrobial drug Metronidazole (MNZ) for topical delivery for the treatment of periodontitis. It is demonstrated that cyclodextrin nanogel (nGel) loaded with metronidazole provides an efficient drug delivery route but also has potential clinical applications and offers

Synthesis and properties of lipoamino acid/fatty acid mixtures. Influence of the amphiphilic structure. [PDF]

open access: yes, 2009
The acylation of amino acids by acid chlorides with from 8 to 12 carbon atoms, in alkaline aqueous medium following Shotten-Baumann reaction, results in sodium salts of Nα-acylamino acids and fatty acids mixture. These lastest are present in proportion
