In this paper, we demonstrate the encapsulation of cells or individual cell spheroids within nanoliter-scale hydrogels. This method enables on-demand immobilization of cells or cell spheroids on an array slide, facilitating subsequent culturing, washing, or immersion into media without cell detachment. The selective gelation of individual droplets is particularly interesting, as it allows for sorting cells or single-cell spheroids by stabilizing desired droplets while removing unwanted spheroids from the surface through simple washing. This approach holds potential for high-throughput cell screenings and miniaturized workflows in 3D microenvironments, advancing research in fields such as cell, spheroid or organoid screenings, drug discovery, and precision medicine.

Ever wondered how to perform tens of thousands of nanoliter droplet manipulations in a truly parallel fashion? Here we show a method that enables parallel medium exchange in thousands of nanoliter-scale cell cultures, facilitates the extraction of nanoliter-sized aliquots from thousands of nanodroplets, and allows for the simultaneous transfer of single-cell spheroids between individual 200 nL droplets—in seconds and across thousands of droplets at once! 💪

We have enhanced the temperature responsiveness of poly(N-isopropylacrylamide) (PNIPAM) hydrogels by incorporating hierarchical porosity into the polymer. Nanometer-sized pores were created through polymerization-induced phase separation, while larger pores were formed using 3D printing. This has resulted in PNIPAM 3D structures that exhibit very fast temperature-responsiveness, despite their macroscopic size. Check out our latest paper. Read the full article here.

In this work, we continued to develop the method for fabricating functional porous 3D structures. In this ChemComm paper, we extended our approach to the thiol-ene chemistry, which surprisingly enhanced the mechanical properties of the macroporous 3D structures, compared to their polymethacrylate counterparts. More details in the publication: „3D printing of reactive macroporous polymers via thiol-ene chemistry and polymerization-induced phase separation“. Congratulations to Nikolaj K Mandsberg and Fatma Aslan! ???? Read the full article here.
