This protocol presents a method to analyze the emission of 3D printing pens. Particle concentration and particle size distribution of the released particle is measured. Released particles are further analyzed with transmission electron microscopy (TEM). Metal content in filaments is quantified by inductively coupled plasma mass spectrometry (ICP-MS).

In this article a high-throughput protocol for fast and reliable determination of gene expression levels in single or bulk C. elegans samples is described. This protocol does not require RNA isolation and produces cDNA directly from samples. It can be used together with high-throughput multiplexed nanofluidic real-time qPCR platforms.
FAQs
The key tissue response is protein denaturation at the heated metal tip, followed by sealing of small blood vessels. This converts electrical energy into localized thermal hemostasis at the contact site. In neurosurgical settings, that response can reduce bleeding in the operative area and help preserve visibility while surgeons work around delicate brain or spinal tissues.
Temperature, contact time, and pressure jointly determine how much thermal energy reaches tissue. Increasing or prolonging these conditions can intensify the local effect, whereas careful control helps confine treatment to the intended area. This balance is especially important near neural structures, where unnecessary heat may cause collateral injury even when hemostasis is achieved.
Excessive heat can extend thermal injury beyond the intended treatment site and damage nearby neural structures. The risk makes controlled energy delivery essential when working in or near the brain and spinal tissues. Maintaining appropriate temperature, contact time, and pressure supports bleeding control while reducing unintended effects on surrounding tissue.
When the heated metal tip contacts tissue, thermal energy produces localized protein denaturation. The resulting tissue change helps seal small blood vessels and control bleeding at the contact point. Because the effect is concentrated where the tip meets tissue, the instrument can contribute to a clearer operative field during precise surgical work.
In neuroscience and neurosurgery, the instrument is applied to help control bleeding during procedures involving delicate brain or spinal tissues. By supporting hemostasis, it helps maintain a clear operative field, which is important for microsurgical precision. Its use requires attention to thermal exposure because nearby neural structures may be vulnerable to excessive heat.
Its main benefit is precise hemostasis that supports visibility during surgery, particularly where bleeding can interfere with work on delicate neural tissues. The principal limitation is thermal spread: excessive heat, prolonged contact, or inappropriate pressure may injure nearby structures. Thus, the instrument supports microsurgical control only when energy delivery remains carefully managed.
