The impact of electrostatic attraction on the uptake of gold nanoparticles (AuNPs) into positively charged strong poly-[2-(Methacryloyloxy) ethyl] trimethylammonium chloride (PMETAC) polyelectrolyte brushes was investigated. In this work, PMETAC brushes were synthesized via surface-initiated atom transfer radical polymerization (Si-ATRP). PMETAC/AuNP composite materials were prepared by incubat...

1. When a solution of a salt of gelatin or crystalline egg albumin is separated by a collodion membrane from a watery solution (free from protein) a potential difference is set up across the membrane in which the protein is positively charged in the case of protein-acid salts and in which the protein is negatively charged in the case of metal proteinates. The turning point is the isoelectric po...

In this paper, a control algorithm is proposed for pH sensitive nanorobots to deliver drugs in the tumor area while navigating in the blood stream environment. The nanorobots are able to communicate with their neighbors using the Particle Swarm Optimization algorithm. Furthermore, the obstacle avoidance algorithm allows the nanorobots to avoid collision with the blood cells. Each nanorobot can ...
