New Green Chemistry Lab paper!

March 27, 2019

Our latest research entitled "Starch-mediated synthesis of mono- and bimetallic silver/gold nanoparticles as antimicrobial and anticancer agents" has been published in the International Journal of Nanomedicine. Good job team!


Background and aim: Bimetallic silver/gold nanosystems are expected to significantly improve therapeutic efficacy compared to their monometallic counterparts by maintaining the general biocompatibility of gold nanoparticles (AuNPs) while, at the same time, decreasing the relatively high toxicity of silver nanoparticles (AgNPs) toward healthy human cells. Thus, the aim of this research was to establish a highly reproducible one-pot green synthesis of colloidal AuNPs and bimetallic Ag/Au alloy nanoparticles (NPs; Ag/AuNPs) using starch as reducing and capping agent. 
Methods: The optical properties, high reproducibility, stability and particle size distribution of the colloidal NPs were analyzed by ultraviolet (UV)–visible spectroscopy, dynamic light scattering (DLS) and ζ-potential. The presence of starch as capping agent was determined by Fourier transform infrared (FT-IR) spectroscopy. The structural properties were studied by X-ray diffraction (XRD). Transmission electron microscopy (TEM) imaging was done to determine the morphology and size of the nanostructures. The chemical composition of the nanomaterials was determined by energy-dispersive X-ray spectroscopy (EDS) and inductively coupled plasma mass spectrometry (ICP-MS) analysis. To further study the biomedical applications of the synthesized nanostructures, antibacterial studies against multidrug-resistant (MDR) Escherichia coli and methicillin-resistant Staphylococcus aureus(MRSA) were conducted. In addition, the NPs were added to the growth media of human dermal fibroblast (HDF) and human melanoma cells to show their cytocompatibility and cytotoxicity, respectively, over a 3-day experiment.
Results: UV–visible spectroscopy confirmed the highly reproducible green synthesis of colloidal AuNPs and Ag/AuNPs. The NPs showed a face-centered cubic crystal structure and an icosahedral shape with mean particle sizes of 28.5 and 9.7 nm for AuNPs and Ag/AuNPs, respectively. The antibacterial studies of the NPs against antibiotic-resistant bacterial strains presented a dose-dependent antimicrobial behavior. Furthermore, the NPs showed cytocompatibility towards HDF, but a dose-dependent anticancer effect was found when human melanoma cells were grown in the presence of different NP concentrations for 72 hours.
Conclusion: In this study, mono- and bimetallic NPs were synthesized for the first time using a highly reproducible, environmentally friendly, cost-effective and quick method and were successfully characterized and tested for several anti-infection and anticancer biomedical applications.

Green Chemistry Lab Recent Publication

March 11, 2019

The Green Chemistry Lab is celebrating the recent publication of “Citric juice-mediated synthesis of tellurium nanoparticles with antimicrobial and anticancer properties” in the Green Chemistry Journal, part of the Royal Society of Chemistry. 


Bacterial infections and cancer are two of the most significant concerns that the current healthcare system should tackle nowadays. Green nanotechnology is presented as a feasible solution that is able to produce materials with significant anticancer and antibacterial activity while overcoming the main limitations of traditional synthesis. In the present work, orange, lemon, and lime extracts were used as both reducing and capping agents for the green synthesis of tellurium nanoparticles (TeNPs) using a microwave-assisted reaction. TeNPs showed a uniform size distribution, and rod- and cubic-shapes, and were extensively characterized in terms of morphology, structure and composition using TEM, SEM, XPS, XRD, FTIR and EDX analysis. TeNPs showed an important antibacterial activity against both Gram-negative and -positive bacteria in a range concentrations from 5 to 50 μg mL−1 over a 24-hour time period. Besides, nanoparticles showed an anticancer effect towards human melanoma cells over 48 hours at concentrations up to 50 μg mL−1. Moreover, the Te nanostructures showed no significant cytotoxic effect towards human dermal fibroblast at concentrations up to 50 μg mL−1. Therefore, we present an environmentally-friendly and cost-effective synthesis of TeNPs using only fruit juices and showing enhanced and desirable biomedical properties towards both infectious diseases and cancer.

RISE 2018 Expo at Northeastern University

April 5, 2018

At RISE, 2000+ industry leaders, entrepreneurs, investors, researchers, and technology enthusiasts from diverse sectors engage more than 400 of Northeastern’s solution-focused innovation. Several members of our Green Team assisted to the conference with the aim to show their research and establish new collaboration lines. 

David Medina presented a review of his last paper focused on the synthesis of metallic nanoparticles using bacteria. A pretty similar approach was used by Miguel Angel Alvarez to show ho cancer cells can be used for generation of metallic nanoparticles.

Ada Vernet exhibited a promising plan for the use of green tellurium nanowires as biocompatible agents and templates for nanoparticles synthesis. The method of bacteria and bacterial biomass to clean contaminated environments was the bullet point of the poster made by Claudia Isern.

Lorena Baranda showed how bimetallic nanoparticles could be straightforwardly produced by bacteria. William Teen-Street presented an easy and cost-effective method to synthesize metallic nanoparticles with both antibacterial and anticancer properties using orange juices. And Christopher Brown explain how tellurium nanoparticles with a robust anticancer ability can be produced using a green approach in hydrothermal reactors. 

The team was successful again, and we are looking forward a new chance to show the world the potential of our research.
