Both immobilization types exhibited similar high releaseate bioactivity profiles and a sustained delivery of rhBMP-2.
A novel hydrogen sulfide microbial biosensor was developed based on investigating the influence of four design parameters: cell concentration, immobilization bed type, hydrogen sulfide concentration, and geometrical shape of the biosensor.
The prescribed orthoses design will be in neutral wrist position, called immobilization splint, type 0, with the aim to reduce carpal intratunnel pressure and prevent from flexion posture, during night for 6 weeks.
However, each system has unique immobilized enzyme characteristics depending on factors such as enzyme source, support type, immobilization method, and enzyme-support interaction [ 29, 30].
The present study was designed to identify afferents of the PVT, which are activated by an immobilization stress, one type of the 'neurogenic' stress paradigms, using combined Fos immunohistochemistry and retrograde tracing experiments with cholera toxin B subunit.
First, PCL scaffolds with a 0/90° lay-down pattern (0/90) were plotted and subjected to an oxygen plasma (O2) or multistep surface modification, including post-argon 2-amino-ethylmethacrylate grafting (AEMA), followed by immobilization of gelatin type B (gelB) and physisorption of fibronectin (gelB Fn).
New hybrid olefin metathesis catalysts were prepared by immobilization of Hoveyda Grubbs type catalyst (commercially available as Zhan catalyst-1B) on the surface of mesoporous molecular sieves differing in pore size and architecture (MCM-41, MCM-48, and SBA-15) and conventional silica for a comparison.

To investigate the influence of the electrode structure and the immobilization procedure, two types of enzymatic electrodes have been developed.
In this work, a strategy for preparing polyethylene glycol (PEG) coatings for subsequent hapten immobilization on glass-type silica surfaces is presented and characterized in detail.
