Developing a catalytic nanoenzyme activated by the tumor microenvironment (TME) shows excellent potential for in situ cancer treatment. However, the rational design of a cascade procedure to achieve high therapeutic efficiency remains challenging. In this study, the colorectal TME-responsive multifunctional cascade nanoenzyme CuO@MnO@glucose oxidase (GOx)@hyaluronic acid (HA) was developed to target in situ cancer starvation/chemodynamic therapy (CDT)/photothermal therapy (PTT).

The tumor microenvironment (TME) is characterized by several key features, including hypoxia, elevated levels of hydrogen peroxide (HO), high concentrations of glutathione (GSH), and an acidic pH. Recent research has increasingly focused on harnessing or targeting these characteristics for effective cancer therapy. In this study, we developed an innovative composite bio-reactor that integrates genetically engineered bacteria with upconversion nanoparticles (UCNPs) and nano-copper manganese materials for lung cancer treatment.

Targeting the peculiarities of tumor tissue microenvironment different from normal tissue, such as lower pH and overexpression of hydrogen peroxide is the key to effective treatment. In this study, acid-responsive Z-scheme heterojunctions polyglycolated MoS/CoFeO (MoS = molybdenum disulfide, CoFeO = cobalt ferrite) was synthesized using a two-step hydrothermal method, designated as MSCO-PEG, guided by dual modes of photoacoustic imagine (PAI) and nuclear magnetic imaging (MRI). MSCO-PEG (PEG = polyethylene glycol) responded to the acidic environment of tumor tissues and overexpression of hydrogen peroxide to turn on multimodal synergistic treatment of tumor cells under near-infrared-II (NIR-II) illumination.

The impact of animal-based food production on climate change drives the development of plant-based alternatives. We demonstrate the use of colloidal thermogelation on a real nanoemulsion system to create structured gels that could be of interest for thermo-mechanical processing of next-generation plant-based food applications. We use a commercial pea protein isolate (PPI) without further purification to stabilize a 20 vol% peanut oil-in-water nanoemulsion at pH = 7 by high-pressure homogenization (HPH) and demonstrate the temperature induced gelation behavior of the nanoemulsion as a function of the HPH processing parameters.

The aim of this study is to explore and evaluate recent innovations in drug delivery systems (DDS) for biologics, focusing on enhancing stability and targeted delivery to improve the efficacy and safety of next-generation therapeutics. The most recent developments in a variety of DDS, such as nanoparticles, microneedles, hydrogels, and biodegradable polymers, were examined in depth. Information from peer-audited diaries, clinical preliminaries, and mechanical reports were blended to survey the presentation of these frameworks concerning dependability, designated conveyance, patient consistence, and controlled discharge.
