Evaluating embryo quality with ultrasensitive protein detection

Infertility is estimated to affect 9% of reproductive-aged couples globally, and many couples turn to assisted reproductive technology. Selecting embryos with maximum development potential plays a pivotal role in obtaining the highest rate of success. Researchers can evaluate the quality of an embryo by detecting the content of proteins secreted. In Biomicrofluidics, a method to detect trace proteins secreted by embryos using microfluidic droplets and multicolor fluorescence holds promise to select embryos for ART.
