Fast and effective transportation of beads/molecules into living cells with high cell viability is essential for drug development and cell biology. This study presents a new approach of injecting single magnetic nanobeads with low surface temperature into living cells using a continuous-wave laser. Experimental results demonstrate the successful injection of magnetic nanobeads into living cells with high injection rates reaching 100%, short injection times of about 1 sec, and maximal cell survival rates of 100%.
