Functionality and degradation of 3D-printed polymeric scaffolds for mandibular reconstruction and vascularized bone tissue repair

Bulusu K.V., Holmes B., Paulson P., Zhang L.G., Plesniak M.W., The George Washington University, US

One of the greatest challenges in field of maxillofacial and craniofacial reconstruction is to quickly and adequately induce a vascular network within any large sections of repaired bone tissue. In this study we are addressing [...]

Studying the Microalgae Growth and Stable Nanoemulsion Production Systems for Environmental Mitigations

Chinni G., Subeshan B., Rahman M.M., Asmatulu R., Wichita State University, US

Recently, environmental concerns have been rising in the world because of the greenhouse gasses, such as CO2, N2O, CH4, and fluorinated gases and industrial products, which in turn cause irreversible climate changes. Algal oils are [...]

Acne Treatment based on Selective Photothermolysis of Sebaceous Follicles with Topically Delivered Gold Plasmonic Particles

Paithankar D., Meyer T., Blomgren R., Faupel L., Lando A., Anderson R., Sebacia, Inc., US

A laser treatment for acne, one of the most common dermatologic conditions, with 150 nm diameter plasmonic resonant particles tuned to absorb near infrared light has been developed. Acne lesions originate from sebaceous follicles; the [...]

A plasma electrochemistry reactor for the synthesis of radioactive gold nanoparticles

Fortin M.-A., Bouchard M., Laprise-Pelletier M., Turgeon S., Université Laval, CA

Abstract: Gold nanoparticles (Au NPs) are increasingly considered for use as radioactive sources (198Au) for prostate brachytherapy procedures [1]-[2]. The range of the 198Au β-particle (0.96 MeV, ~ 11 mm in soft tissue, ~ 1100 [...]

Plasmonic Nanocages as Photothermal Transducers for Nanobubble Cancer Therapy

Karampelas I.H., Liu K., Furlani E.P., University at Buffalo (SUNY), US

The ability to generate and control thermal energy with nanoscale resolution is finding increasing use in a variety of applications spanning the fields of nanoparticle synthesis, nanofabrication, bio-imaging and medical therapy [1, 2]. One of [...]

Gold Nanoshells With Micellar Core for The Delivery of Hydrophobic Chemotherapeutic and Cancer Photothermal Therapy

Lee S-Y, Shieh M.J., National Taiwan University, TW

Gold nanoshells have attracted great research interest because of its potential application in cancer photothermal therapy. In the present study, we established a multifunctional gold nanoshell that directly utilizing positively charged PDMA-b-PCL micelles as a [...]

Dependence of the Energy of Electric Pulse Required to Electroporate the Cell on the Pulse Duration for Pulses from 50 ns to 500 ms

Saulis G., Bitinaitė A., Vytautas Magnus University, LT

To successfully implement the technology of food processing with pulsed electric fields (PEF), it is important to know what particular electric treatment (pulse duration, field strength, etc.) would require the minimum energy. Here, theoretical relationships [...]

Estimation of the Energetic Barrier to Pore Formation and the Pore Radius Corresponding to this Barrier for Different Cell Lines

Bitinaitė A., Saulis G., Vytautas Magnus University, LT

The permeability of the cell membrane can be modified by exposing of cells to high-voltage electric pulses leading to the formation of nanometer-sized pores in the cell membrane (electroporation or nanoporation). This phenomenon is widely [...]
