Size-Dependent In Vivo Transport of Nanoparticles: Implications for Delivery, Targeting, and Clearance

ACS Nano, Journal Year: 2023, Volume and Issue: 17(21), P. 20825 - 20849

Published: Nov. 3, 2023

Understanding the in vivo transport of nanoparticles provides guidelines for designing nanomedicines with higher efficacy and fewer side effects. Among many factors, size plays a key role controlling their behaviors due to existence various physiological thresholds within body size-dependent nano-bio interactions. Encouraged by evolving discoveries nanoparticle-size-dependent biological effects, we believe that it is necessary systematically summarize size-scaling laws nanoparticle vivo. In this review, summarized effect on along journey body: begin administration via different delivery routes, followed targeting intended tissues including tumors other organs, eventually clearance through liver or kidneys. We outlined tools investigating as well. Finally, discussed how may leverage tackle some challenges nanomedicine translation also raised important size-related questions remain be answered future.

Biodistribution, pharmacokinetics and excretion studies of intravenously injected nanoparticles and extracellular vesicles: Possibilities and challenges

Advanced Drug Delivery Reviews, Journal Year: 2022, Volume and Issue: 186, P. 114326 - 114326

Published: May 16, 2022

There is a large interest in developing nanoparticles and extracellular vesicles for delivery of therapeutics or imaging agents. Regulatory approval such products requires knowledge about their biodistribution, metabolism excretion. We here discuss possibilities challenges methods used studies, which most often are performed after labelling with radioactive isotopes fluorescent molecules. It important to evaluate if the labelled unlabeled can be expected behave similarly body. Furthermore, one needs critically consider whether labels still associated product at time analyses. advantages disadvantages different modalities as PET, SPECT, MRI, CT, ultrasound optical whole-body describe how estimate amount harvested organs tissue.

Hydrogen sulfide (H2S) is an important signaling molecule in colorectal cancer (CRC). It produced the colon by catalytic synthesis of colonocytes' enzymatic systems and release intestinal microbes, oxidatively metabolized mitochondria. Both endogenous H2S colonic epithelial cells exogenous lumen contribute to onset progression CRC. The up-regulation synthetases thought be cause elevated levels CRC cells. Different diagnostic probes combination therapies, as well tumor treatment approaches through modulation, have been developed recent years become active area investigation for diagnosis In this review, we focus on specific mechanisms production oxidative metabolism function occurrence, progression, diagnosis, We also discuss present challenges provide insights into future research burgeoning field.

Confining Prepared Ultrasmall Nanozymes Loading ATO for Lung Cancer Catalytic Therapy/Immunotherapy

Advanced Materials, Journal Year: 2023, Volume and Issue: 35(45)

Published: Sept. 25, 2023

Nanozymes with inherent enzyme-mimicking catalytic properties combat malignant tumor progression via therapy, while the therapeutic efficacy still needs to be improved. In this work, ultrasmall platinum nanozymes (nPt) in a confined domain of wormlike pore channel gold nanobipyramidal-mesoporous silica dioxide nanocomposites, producing nanozyme carriers AP-mSi photoenhanced peroxidase ability, are innovatively synthesized. Afterward, based on prepared AP-mSi, lung-cancer probe (AP-HAI) is ingeniously produced by removing SiO2 template, modifying human serum albumin, and loading atovaquone molecules (ATO) as well IR780. Under NIR light irradiation, inner AuP IR780 collaborate for photothermal process, thus facilitating peroxidase-like process H2 O2 . Additionally, loaded ATO, cell respiration inhibitor, can impair metabolism cause oxygen retention, hence enhancing IR780's photodynamic therapy (PDT) effectiveness. As result, PDT nPt nanozymes' ability endow probes high ROS productivity, eliciting antitumor immune responses destroy tissue. Systematic studies reveal that obvious reactive species (ROS) generation obtained strategy using reducing consumption which turn enables synergetic therapy/immunogenic-cell-death-based immunotherapy. The results work would provide theoretical justification practical use probes.
