We here report improved synthesis and in vitro interactions of amphiphilic hydrogel nanoparticles with the macrophage cell line J774A.1. Nanoparticles comprising dispersed hydrophobic nanodomains of poly(propylene glycol) within a continuous phase of hydro ...
Biocompatible Au nanoparticles with surfaces modified by PEG (polyethylene glycol) were developed in view of possible applications for the enhancement of radiotherapy. Such nanoparticles exhibit preferential deposition at tumor sites due to the enhanced pe ...
The mis-regulation of gene transcription in the living cell can be the cause of complex human diseases like cancer. One challenge of the post-genomic era of biomedical research is the development of in vitro techniques for the rapid and cost-effective anal ...
Polymers have been extensively utilized in the design of nanometer-sized delivery vehicles of chemotherapeutics for clinical cancer therapy. Polymeric nanoparticulate delivery vehicles, with chemotherapeutics being either conjugated or encapsulated, have b ...
Polymeric nanoparticle technology has evolved from drug carrier design to advanced multifunctional macromolecular structures. They enable drug delivery and release of a bioactive under spatio-temporal control rather than just passive release by a long-circ ...
The goals of tissue engineering include recapitulating specific tissue functions for regenerative medicine and developing in vitro models of human tissues to study human physiology and pathophysiology and for testing and screening drugs before expensive cl ...
We present an experimental and theoretical study on the optical properties of arrays of gold nanoparticle in-tandem pairs (nanosandwiches). The well-ordered Au pairs with diameters down to 35 nm and separation distances down to 10 nm were fabricated using ...
Tumor-infiltrating myeloid cells, including tumor-associated macrophages (TAMs), have been implicated in tumor progression. We recently described a lineage of mouse monocytes characterized by expression of the Tie2 angiopoietin receptor and required for th ...
Head and neck (H&N) cancer patients have a high incidence of second primary tumors in the tracheobronchial tree. Diagnostic autofluorescence endoscopy (DAFE) has shown promising results in the detection of early neoplastic and pre-neoplastic changes in the ...
Effective interstitial transport of particles is necessary for injected drug/diagnostic agents to reach the intended target; however, quantitative methods to estimate such transport parameters are lacking. In this study we develop an in vivo model for eval ...
