Hypoxia severely limits the antitumor immunotherapy for breast cancer. Although efforts to alleviate tumor hypoxia and drug delivery using diverse nanostructures achieve promising results, creation of a versatile controllable oxygen-releasing nano-platform co-delivery with immunostimulatory molecules remains persistent challenge. To address this problem, oxygen releasing vehicle PFOB@F127@PDA (PFPNPs) is developed, which effectively co-delivered either protein lactate oxidase (LOX) or...
