Manipulating tiny amounts of liquids (droplets), gas samples (bubbles), or even small quantities of solids on surfaces is a huge challenge. However, it is of paramount importance for diagnostics, analytics, lab-on-a-chip applications, and miniaturization in general.
In this paper, we introduce a new, simple yet powerful method: CART (Carrier-based Actuatable and Reprogrammable Transport). This method allows for the manipulation of small droplets, bubbles, and tiny solid samples. It has the advantage of not depending on the type of surface and type of cargo, as we use tiny magnetically actuatable “boats” or CARTs that effortlessly transport droplets, bubbles, or solids across different solid surfaces and even liquid interfaces, whether flat or curved! 🤯
Congrats to Nikolaj K Mandsberg and Julián A. Serna! 💪🫶

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.
