A flexible and stretchable field-effect transistor (FET) is an essential element in a number of modern electronics. To realize the potential of this device in harsh real-world conditions and to extend its application spectrum, new functionalities are needed to be introduced into the device. Here, solution-processable elements based on carbon nanotubes that empower flexible and stretchable FET with high hole-mobility (µ ≈ 10 cm V s ) and relatively low operating voltages (<8 V) and that retain self-healing properties of all FET components are reported.

For radical resection of squamous cell carcinoma of the oral cavity, a tumor free margin of at least 5 mm is required. Unfortunately, establishing in-depth margins is a surgical conundrum. Knowing the hybrid sentinel node (SN) tracer indocyanine green (ICG)-Tc-nanocolloid generates temporary tattoo-like markings at the site of administration, we studied the ability of applying this tracer for tumor-margin demarcation combined with SN biopsy.

The Koebner phenomenon is the development of lesions in traumatized skin, often with spontaneously occurring lesions elsewhere. We report a case of a woman in her 20 s presenting with discoid lesions superimposed on tattoos that she obtained many years ago. Although a few case reports have been published describing development of lesions on red tattoos attributed to photosensitivity, or koebnerization occurring less than a month following tattoo placement, our patient demonstrates a unique delayed development of discoid lesions years after obtaining her tattoos in non-sun exposed skin.

What is the meaning of piercing and tattoo in sixteen years old? What are the deep reasons, affective and relational, that explain the explosion of this "fashion" among teenagers? The recent spread of these practices among young people and very young people offered the opportunity to reflect on the value attributed to the body manipulation in teenager growth context. Inked bodies, pierced, and other similar manipulations, express a communicative intention, whose strength is proved by the violence of these practices. The sense of the message, however, risks remaining obscure to adults, who lack the tools to decode it. Read More

Endoscopic colorectal tattooing with carbon-based dyes is commonly employed in order to assist with later localization of the lesion. Although carbon is thought to be nontoxic, there usually is some inflammatory reaction with fibrosis and granuloma formation after tissue injection. The aim of this report is to alert to a possible underestimated, late consequence of colorectal carbon-based marker tattooing, namely pronounced fibrosis at the site of the injection that could lead to a blurring and misinterpretation of changes evaluated by radiological techniques.

People have tattooed themselves for thousands of years, and it remains popular with various groups across mainstream society. Although many people choose tattoos that express their life philosophy, epic events in their life, or their personal mantra, the use of tattooing in medicine such as a "do not resuscitate" tattoo is increasingly becoming more common (; ). As these tattoos do not meet the legal requirements for an advance health directive, they are at best a guide to the person's wishes and at worst a useless, painful exercise. Read More

Background And Objectives: Cutaneous pigmentary disorders are both more common and more difficult to treat in patients with skin color given the higher melanin content in the epidermis. Although Q-switched lasers are widely considered to be the standard treatment for both epidermal and dermal pigmentary conditions, a very high risk of post-inflammatory hyperpigmentation (PIH) of up to 25% is seen in patients with skin of color. Recently, the novel picosecond laser with pulse durations operating at sub-nanosecond domains has been shown to be effective in tattoo removal and in the treatment of acne scars. Read More

We introduce a soft ultrathin and stretchable electronic skin with surface-mounted components that can be transferred and wrapped around any three-dimensional (3D) surface or self-adhere to the human skin. The ∼5 μm thick circuit is fabricated by printing the pattern over a temporary tattoo paper using a desktop laser printer, which is then coated with a silver ink and eutectic gallium-indium (EGaIn) liquid metal alloy. The resulting "Ag-In-Ga" traces are highly conductive and maintain low electrical resistivity as the circuit is stretched to conform to nondevelopable 3D surfaces. Read More
