Percutaneous Intratumoral Immunoadjuvant Gel Increases the Abscopal Effect of Cryoablation for Checkpoint Inhibitor Resistant Cancer
Published 2024“…To address these shortcomings, an injectable thermoresponsive gel‐based controlled release formulation is developed for the FDA‐approved Toll‐like‐receptor 7 (TLR7) agonist imiquimod (“Imigel”) that forms a tumor‐resident depot upon injection and contains a contrast agent for visualization under computed tomography (CT). The poly‐lactic‐<jats:italic>co</jats:italic>‐glycolic acid‐polyethylene glycol‐poly‐lactic‐<jats:italic>co</jats:italic>‐glycolic acid (PLGA‐PEG‐PLGA)‐based amphiphilic copolymer gel's underlying micellar nature enables high drug concentration and a logarithmic release profile that is additive with the neo‐antigen release from cryoablation, requiring only a single injection. …”

Cake formation of bidisperse suspensions in dead-end microfiltration
Published 2021“…The evolution of the cake during dead-end microfiltration of different compositions of bidisperse feeds was investigated using network modeling and three-dimensional (3D) optical coherence tomography (OCT) imaging. The foulant particles were latex of two different sizes (namely, 3 and 5 µm) and the membrane was polycarbonate track-etched with nominal diameter of 2 µm. …”

Fouling and mitigation mechanisms during direct microfiltration and ultrafiltration of primary wastewater
Published 2022“…Several types of MF and UF membranes were examined by threshold flux determination, and two types of membranes (MF, 0.08 μm; UF, 100 kDa) were chosen for exploring membrane fouling mechanisms at different feed pressures via both fouling resistance analysis and optical coherence tomography (OCT) observation. The results revealed that both MF and UF displayed three-stage fouling behaviors, i.e., initial intermediate pore blocking followed by two-stage cake filtration. …”

Towards indicating human skin state in vivo using geometry-dependent spectroscopic contrast imaging
Published 2022“…We previously reported on geometry-dependent spectroscopic contrast achieved by spectroscopic micro-optical coherence tomography (SμOCT), which discovered that transversely oriented and regularly arranged nano-cylinders selectively backscatter the long-wavelength lights and generate spectral centroid (SC) shifts towards the long wavelengths within a spectral window of 700 - 950 nm. …”
