Opto-microfluidic assisted synthesis of photo-protoporphyrin (pPP) conjugated to hollow gold-albumin hybrid nanoshells to enhance the efficiency of photodynamic therapy of triple negative breast cancer cells.

Introduction: Protoporphyrin-IX (PpIX), a photosensitizer used in photodynamic therapy, has limitations due to its hydrophobicity, rapid photobleaching, and low absorption peak in the red region. These limitations make the use of PpIX less effective for photodynamic therapy treatments. In this study, we harnessed the power of microfluidic technology to manipulate the properties of PpIX and quickly synthesize albumin-based hybrid nanoshells with high reproducibility.

A microfluidic electrochemical aptasensor for highly sensitive and selective detection of A549 cells as integrin α6β4-containing cell model via IDA aptamers.

There is a growing interest in developing microfluidic biosensors for the accurate and reproducible analysis of various biomarkers obtained from liquid biopsy. This paper reports a novel microfluidic electrochemical aptasensor for determination of A549 cells as integrin α6β4-containing cell model and circulating tumor cell (CTC) model of NSCLC, based on target-induced structure switching mode. The conformational change of IDA aptamer structure with an affinity towards A549 cells, in the absence and presence of A549 cells allowed selective and sensitive detection of A549 cells.

A whole-thermoplastic microfluidic chip with integrated on-chip micropump, bioreactor and oxygenator for cell culture applications.

Microfluidics provides enabling platforms for various cell culture, drug testing and synthesis of drug carriers using chip-based microsystems. In this study, we present a novel integrated whole-thermoplastic microfluidic chip to provide a platform for on-chip cell culture at static and dynamic conditions. The whole chip was made of polymethyl methacrylate (PMMA) and thermoplastic polyurethane (TPU) using high precision micromilling and laser micromachining, assembled by thermal fusion bonding.
