Polydiacetylene (PDA) materials are used as a platform for detection of biological analytes
such as microorganisms, viruses and proteins. The environmentally responsive chromic and …

Polydiacetylene (PDA) has attracted interest for use as a sensing platform in biomedical,
environmental, and chemical engineering applications owing to its capacity for colorimetric …

Polydiacetylenes are a class of polymers with unique optical properties. Upon
photopolymerization, monomers form a deep blue, nonfluorescent polymer, which …

“Naked eye” color detection of proteins was achieved by embedding calixarene receptors
within vesicles comprising phospholipids and the chromatic polymer polydiacetylene …

We report a new polydiacetylene (PDA) sensor strip for simple visual detection of zinc ions
in aqueous solution. The specificity of this sensor comes from Zn 2+ DNA aptamer probes …

The bactericidal activity of mouse α-defensins (cryptdins) requires proteolytic activation of
inactive precursors by matrix metalloproteinase-7 (matrilysin, EC 3.4. 24.23, MMP-7 a). To …

Polydiacetylenes are chromatic conjugated polymers formed upon the photopolymerization
of self-assembled diacetylenes. They exhibit conformation-dependent colorimetric …

Membrane binding and relative penetration of indolicidin analogs were studied using
lipid/polydiacetylene (PDA) chromatic biomimetic membranes. Colorimetric and …

Micro-arrayed polydiacetylene (PDA) vesicles mixed with phospholipids on glass slides
were prepared for label-free detection of Escherichia coli. When E. coli bound to its …

Characterization of membranes and of biological processes occurring within membranes is
essential for understanding fundamental cellular behavior. Here we present a detailed …
