Environmental Behaviors and Biological Effects of Engineered Nanomaterials: Important Roles of Interfacial Interactions and Dissolved Organic Matter

Abstract

What is the most favorite and original chemistry developed in your research group? Nanomaterial pollution chemistry. How do you get into this specific field? Could you please share some experiences with our readers? I started to work on nanomaterial pollution chemistry during my visiting scholar research (2006-2008) in UMass, Amherst, USA. There, I studied chemistry involved in environmental behaviors and biological effects of nanomaterials. Thereafter, this becomes the major research topic in my lab till now. How do you supervise your students? Talk and discuss with them about their research regularly. Being prepared before giving comments or suggestions on their research results to make my viewpoints helpful. Share relevant and latest references with them. Appropriately push them to read, think, and do more. Encourage them to ask more questions about experimental phenomena. Inspire their ambition to publish good papers and become good scientists. What is the most important personality for scientific research? Hungering for truth and novelty.

Balancing and Therapeutic Roles of CXCR4‐Inhibiting Nanomedicine via Synergetic Regulation of Hepatic Stellate Cells and Extracellular Matrix in Liver Injury†

“…PAMD/Zn exacerbated inflammation by recruiting inflammatory cells and promoting inflammatory response, while PAMD/Zn reversed fibrosis by lowering CXCR expression and inhibiting the activation of HSCs at different stages. [ 44‐45 ] Therefore, we propose that patients with liver inflammation or/and liver fibrosis, who may benefit from CXCR4 antagonist, should first be examined on the diagnosis and fibrosis staging. Controlling the timing and taking into account the individual differences of each patient is critical for CXCR4 antagonist in clinical application.…”

α-Fe2O3 nanomaterials strengthened the growth promoting effect of Pseudomonas aurantiaca strain JD37 on alfalfa via enhancing the nutrient interaction of the plant–rhizobacteria symbiont

“…26,27 When applied into soil, Fe-based NMs could interact with plant root secretions, soil microorganisms and other soil components, and thus affect host plant growth. [28][29][30] For instance, Fe 3 O 4 NMs significantly promoted maize growth and altered the metabolite composition of leaves, roots and soil, 31 which may be related to the alteration of the soil microbial community structure, and increased the relative abundance of potential PGPR. 32 A previous study showed that α-Fe 2 O 3 NMs exhibited the most significant growth-promoting effect on alfalfa among various Fe-based nanomaterials.…”

Synergistic Effect of Soil Organic Matter and Nanoscale Zero-Valent Iron on Biodechlorination

“…SOM composed of redox-active natural organic macromolecules with abundant functional groups (e.g., carboxyl, phenolic hydroxyl, and quinonyl) is ubiquitous in the environment. , It may interact with indigenous dechlorinating bacteria and nZVI and then alter the degradation of OCs. ,, In some cases, SOM can act as a carbon source and promote microbial reproduction, facilitating the biodegradation of OCs . There are two hypotheses on the influences of SOM on nZVI performance .…”
