On Effect of Chloroform on Electrical Activity of Proteinoids

  • Panagiotis Mougkogiannis and
  • Andrew Adamatzky

Proteinoids, or thermal proteins, produce hollow microspheres in aqueous solutions. Ensembles of the microspheres produce endogenous spikes of electrical activity, similar to that of neurons. To make the first step toward the evaluation of the mechan...

Polymorphism in Glu-Phe-Asp Proteinoids

  • Panagiotis Mougkogiannis and
  • Andrew Adamatzky

Glu-Phe-Asp (GFD) proteinoids represent a class of synthetic polypeptides capable of self-assembling into microspheres, fibres, or combinations thereof, with morphology dramatically influencing their electrical properties. Extended recordings and det...

Proteinoid Polymers and Nanocapsules for Cancer Diagnostics, Therapy and Theranostics: In Vitro and In Vivo Studies

  • Ella Itzhaki,
  • Yuval Elias,
  • Neta Moskovits,
  • Salomon M. Stemmer and
  • Shlomo Margel

Proteinoids—simple polymers composed of amino acids—were suggested decades ago by Fox and coworkers to form spontaneously by heat. These special polymers may self-assemble in micrometer structures called proteinoid microspheres, presented...

Tumor-Targeted Fluorescent Proteinoid Nanocapsules Encapsulating Synergistic Drugs for Personalized Cancer Therapy

  • Ella Itzhaki,
  • Elad Hadad,
  • Neta Moskovits,
  • Salomon M. Stemmer and
  • Shlomo Margel

Personalized cancer treatment based on specific mutations offers targeted therapy and is preferred over “standard” chemotherapy. Proteinoid polymers produced by thermal step-growth polymerization of amino acids may form nanocapsules (NCs) that encaps...

Proto-Neurons from Abiotic Polypeptides

  • Panagiotis Mougkogiannis and
  • Andrew Adamatzky

To understand the origins of life, we must first gain a grasp of the unresolved emergence of the first informational polymers and cell-like assemblies that developed into living systems. Heating amino acid mixtures to their boiling point produces the...
