Carbonyl Iron Foam Surfaces Modified with Poly (L-Lysine) As Smart Surface for Bone Implant

Efficacy of ε-Poly-L-lysine as an Antibacterial Additive for Platelets Stored at Room Temperature

Interaction of Poly-l-lysine with Chromatin

The priming capacity of chromatin of fixed nuclei and chromosomes for exogenous DNA polymerase can be evaluated radioautographically by the incorporation of labeled nucleotides. It had previously been reported that acid fixation or acid treatment of alcohol-fixed tissues led to increased priming when calf thymus DNA polymerases, specific for single-stranded DNA, were used. We employed Escherich...

Control of the Specific Adsorption of Proteins onto Gold Surfaces with Poly( L-lysine) Monolayers

Monolayers of the polypeptide poly(L-lysine) (PL) are used to control the specific adsorption of proteins onto gold surfaces. A PL monolayer modified with biotin is electrostatically adsorbed onto a vapor-deposited gold Eilm that has been coated with a self-assembled monolayer of the alkanethiol 1 1-mercaptoundecanoic acid (MUA). The immobilized biotin moieties act as specific adsorption sites ...

The use of non-viral gene vectors for bioactive poly-(D,L-lactide) implant surfaces in bone tissue engineering.

The application of scaffolds in bone tissue engineering often comes along with side effects such as poor integrity, low regeneration rates of bone tissue with inadequate functionality, and, in case of non-degradable implants, the necessity of a second removal surgery after therapy. In this study, we coated a bioresorbable FDA-approved poly-(ε-caprolactone)-scaffold for bone regeneration with a ...

Oligonucleotide/poly(l-lysine) complexes attachment on poly(styrene/maleic acid) and poly(styrene/maleic anhydride polymeric surfaces

The immobilization efficiency of the complexes of oligonucleotide/poly(L-lysine) onto Poly(Styrene/Maleic Acid), PSMA, and Poly(Styrene/Maleic Anhydride), PSMAA, has been investigated using X-ray photoelectron spectroscopy and atomic force microscopy (AFM) in conjugation with fluorescence-based measurements of DNA attachment. A mono-molecularly thin layer of either electrostatically or covalent...
