It was found that the transition from NH3/Ar to NH3/N2 gas system at other constant processing conditions resulted in increasing the CNT surface roughness, the degree of structural defects, the number of NH2-functional groups connected to the CNT surface and the bio-immobilization capability.
The resulting AuNPs/PDDA-G nanocomposite film exhibited enhanced capability for hemoglobin (Hb) immobilization and realized its direct electrochemistry.
Moreover, Si-based matrixes have been proved to be a very useful support for the immobilization of enzymes thanks to their capability of retaining biological activity[2].
For the purpose of single cell analysis, single cell manipulation capabilities, such as positioning, immobilization, and sorting of target cells, are needed.
By adding biotinylated PEG lipid derivatives that offer targeting capabilities, we demonstrate the immobilization of fluorescent IgG antibodies on stationary PDMS lipid microbubbles through biotin avidin interactions and on-chip trapping for immunoassays.
The capability of the designed SAM in immobilization of organic molecules onto the gold surface was studied utilizing the Michael-addition as a model reaction.
Immobilization of enzymes provides higher stability, reusability and capability to work in aqueous as well as in organic solvents due to protection of enzymes against denaturants, proteolysis and reduced susceptibility to microbial contamination.
The unique capabilities of λ-Exo and its immobilization onto solid supports can serve as a useful tool in the design of biosensors directed toward the sequence analysis of DNAs.
