Article Abstract

Microfluidic-based cytotoxic assays provide high physiological relevance with the potential to replace conventional animal experiments and two-dimensional (2D) assays. Here, a 3D method utilizing a microfluidic platform for analysis of lymphocyte cytotoxicity is introduced in detail, including platform design, cell culture method, real-time cytotoxic assay setup, and image-based analysis. A 2D experimental method is used for comparison, which effectively demonstrates the advantages of 3D microfluidic platforms in closely recapitulating immune responses within the tumor microenvironment. Moreover, a wide range of experimental possibilities and applications using microfluidic 3D cytotoxic assays is introduced in this chapter, along with their capabilities, limitations, and future outlook.

Glioblastoma is a highly malignant brain tumor with few available therapeutic options, for which boron neutron capture therapy (BNCT) has emerged as a promising precision radiotherapy approach. However, its efficacy remains suboptimal due to inadequate tumor targeting of boron agents and lack of in vivo visualization. Herein, a gadolinium-boron integrated lipid nanocarrier (BPA-F&DOTA-Gd@LIPO-ANG) was developed for targeted boron delivery and MRI-guided BNCT.

Enhanced Cancer Radiosensitization via Energy Transfer from Eu-Doped GdF Nanoparticles to Methylene Blue in X-ray Photodynamic Therapy.

We synthesized europium-doped gadolinium fluoride (GdF:Eu) scintillating nanoparticles conjugated to methylene blue (MB) for singlet oxygen (O) generation in X-ray-induced photodynamic therapy (X-PDT). The impact of MB conjugation on GdF:Eu nanoparticles (GdF@B) was analyzed, including size, polydispersity, and surface charge. Time-resolved photoluminescence analysis demonstrated that binding of MB to the nanoparticle surface is essential for enabling efficient resonant energy transfer (ET) from the GdF:Eu core to the MB molecules.

Purpose: Lipopolyplexes (LPP), i.e. hybrid ternary complexes of cationic polymers, nucleic acids and liposomes, represent a second-generation non-viral vector aiming to overcome the limitations of the first-generation polyplexes and lipoplexes like in vivo toxicity and ineffective transfection efficiency.

Block copolymer fluorosurfactants are frequently utilized to stabilize water-oil interfaces in droplet microfluidics, enabling parallel and compartmentalized biochemical reactions within individual droplets. Surfactants are able to self-assemble into inverse micelles with the concentration exceeding the critical micelle concentration (CMC), which has been identified as the main reason causing cross-contamination among droplets. This study explored the possibility to utilize the inverse micelles for passive cargo delivery from the fluorocarbon oil phase into the aqueous droplet interior, which has rarely been studied previously.

Triple-negative breast cancer (TNBC) poses considerable clinical challenges due to its aggressive nature, early metastasis, and limited treatment options. The simplified 2D models and the physiological differences in animal models often result in inconsistent responses to anticancer drugs. To tackle these challenges, three-dimensional (3D) in vitro bioengineered models that accurately replicate the in vivo tumor microenvironment (TME) have been developed, offering a more reliable platform for preclinical drug testing.
