Vaccination dilemma on an evolving social network [PDF]
arXiv, 2019 Vaccination is crucial for the control of epidemics. Yet it is a social dilemma since non-vaccinators can benefit from the herd immunity created by the vaccinators. Thus the optimum vaccination level is not reached via voluntary vaccination at times.

Vaccination strategies and transmission of COVID-19: evidence across advanced countries [PDF]
arXiv, 2021 Given limited supply of approved vaccines and constrained medical resources, design of a vaccination strategy to control a pandemic is an economic problem. We use time-series and panel methods with real-world country-level data to estimate effects on COVID-19 cases and deaths of two key elements of mass vaccination - time between doses and vaccine type.

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks
Advanced Functional Materials, EarlyView.This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

Advanced Healthcare Materials, EarlyView.The new generation nanobomb, termed the stealth nanobomb, is fabricated through self‐assembly using a polymeric carbon monoxide carrier (PLGA(CO)), small molecule near‐infrared‐active agents (2TT‐OC46B), and phospholipid polyethylene glycol (DSPE‐mPEG2000). The stealth nanobomb can circulate in the bloodstream and specifically target pancreatic cancer,

TLR Agonist Nano Immune Therapy Clears Peritoneal and Systemic Ovarian Cancer
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.Intraperitoneal administration of immunogenic Toll‐like receptor agonist‐modified mesoporous silica nanoparticles leads to rapid internalization by ascites myeloid cells with trafficking to fat‐associated lymphoid clusters. Activation of myeloid cells counters suppressive immune mechanisms associated with peritoneal metastasis, leading to regional and ...

Lipid Nanoparticle‐Mediated CRISPR‐Cas13a Delivery for the Control of Bacterial Infection
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.New formulations of lipid nanoparticles (LNPs) that can deliver nucleic acids to Gram‐negative bacteria are proposed to combat bacterial infection. The delivery of nucleic acids by LNPs is aided by LNP‐helpers which weaken the bacterial outer membrane. LNPs encapsulating the Cas13a/gRNA expression vector achieve an antibacterial effect in both in vivo ...
