5-Phenyl-dipyrromethane and 5-(4-pyridyl)-dipyrromethane as modular building blocks for bio-inspired conductive molecularly imprinted polymer (cMIP). An electrochemical and piezoelectric investigation
No full text5-Phenyl-dipyrromethane (5-ph-DP) and 5-(4-pyridyl)dipyrromethane (5-py-DP) are proposed, for the first time, as electroactive building blocks for the preparation of sensors based on molecularly imprinted conductive polymers (cMIP). This paper reports the electrochemical and gravimetric investigation on 5-phenyl-dipyrromethane and 5-(4-pyridyl)dipyrromethane and it demonstrates their ability to form both conductive homo-polymers (cMIP) and co-polymers (co-cMIP). The template salicylic acid (SA) was reversibly and selectively incorporated in the obtained synthetic pockets as proved by both voltammetric and piezoelectric investigation. Moreover, the sensitivity of co-cMIP was higher compared to the two homopolymers. The analytical performances confirm that dipyrromethanes, properly functionalized, can be used as electroactive amino acid-like monomers, to prepare bio-inspired imprinted polymers. © The Royal Society of Chemistry 2015

An Overview of the Application of Blue Light-Emitting Diodes as a Non-Thermic Green Technology for Microbial Inactivation in the Food Sector
Full text linkBlue light is an emerging technology used for the decontamination of food contact surfaces and products. It is based on the activation of photosensitizers by light, determining the release of reactive oxygen species (ROS). ROS causes damage to bacterial cells leading to cell death. Several types of microbes may be treated, such as bacteria, yeasts, moulds and viruses, in planktonic or biofilm form. Blue light technology is affected by several factors: light parameters (i.e., irradiance, dose, wavelength), microbial parameters (i.e., pH, temperature, initial inoculum, grade of biofilm maturation) and surface parameters (i.e., material, roughness, and optical properties). In addition, it may be used alone or coupled with other technologies. The use of blue light shows several advantages, such as safety for food operators, and a lower release of chemicals in the environment. Moreover, it seems unlikely for bacteria to develop resistance to the blue light application

No full textPhotodynamic therapy (PDT) uses nontoxic photosensitizers and visible light to produce reactive oxygen species that kill malignant cells by apoptosis or necrosis. Silencing the antioxidant GSTA1-1 gene by siRNA sensitizes hepatic HepG2 cells to PDT with pentaphyrins. The study is a proof-of-concept for combining PDT with antigene molecules that decrease cellular response to oxidative stress
