Bioactive Glass and Glass-Ceramic Scaffolds for Bone

1. Introduction. Tissue engineering (TE) and regenerative medicine aim to restore diseased or damaged tissue using coinations of functional cells and biodegradable scaffolds made from engineered biomaterials [1,2].Some of the most promising biomaterials for appliion in bone tissue engineering are bioceramics such as hydroxyapatite (HA), calcium phosphates, bioactive glasses and related

Scanning Ion Conductance Microscopy | Annual …

2019-7-17 · Scanning ion conductance microscopy (SICM) is a versatile type of scanning probe microscopy for studies in molecular biology and materials science. Recent advances in feedback and probe fabriion have greatly increased the resolution, stability, and speed of imaging. Noncontact imaging and the ability to deliver materials to localized areas have made SICM especially fruitful for …

aluminum oxide (Al 2O 3, 10 nm)/SiO 2 (50 nm) was used as an electrical insulation layer for the regions that are ~25 m away from the elec-trode tip (figs. S6 and S7). Chronic in vivo biocompatibility assessment We performed in vivo testing using the MiNDS in a series of exper-iments to determine biocompatibility. The astrocytic activity mea-

Peaks in aluminum bound phosphorus (Al-P) and total aluminum (Tot-Al) were observed in three of the four cores analyzed, resulting in an average ratio of added Al to Al-P formed (Al:Al-P) of 112:1. By comparing this ratio to the average ratio of ~11:1 found in other alum-treated Washington lakes, it can be inferred that approximately 10% of the

A toxicity analysis was performed with the marine bioluminescent bacteria Vibrio fischeri. The highest 2,4-D removal efficiency of 99.2% was obtained with the biphasic Au-TiO2(TiO2(B)/anatase) nanobelts with anatase as predominant phase. Toxicity was mainly due to the intermediate 2,4-dichlorophenol (2,4-DCP) which was eliminated in 4 h.

Miniaturized neural system for chronic, local

More effective and better-tolerated pharmacological therapies are needed for neurological disorders. Current treatments often rely on systemic administration, resulting in increased risk of toxicity and adverse effects due to off-target drug distribution.

Beryllium is the smallest of the group II metals — the crystal radius of the divalent ion is only 0.31 A. Beryllium''s ionic charge-to-radius ratio (2/3°) is thus 6.45, similar to that for aluminum (6.0) and much greater than that for the adjacent elements, magnesium (3.1), calcium (2.0), strontium (1.8), barium (1.5), lithium (1.5), and
