Background Despite the wide application of lasers and radiofrequency (RF) surgery in dermatology, it is difficult to find studies showing the extent of damage dependent on cell death. Objective We evaluated histopathologic changes following in vivo thermal damage generated by CO2 laser, 1,444 nm long-pulsed neodymium:yttrium-aluminum-garnet (LP Nd:YAG) laser and RF emitting electrosurgical un...

Cavitation has great application potential in microvessel damage and targeted drug delivery. Concerning cavitation, droplet vaporization has been widely investigated in vitro and in vivo with plasmonic nanoparticles. Droplets with a liquid dodecafluoropentane (DDFP) core enclosed in an albumin shell have a stable and simple structure with good characteristics of laser absorbing; thus, DDFP drop...

The mass spectral detection of low vapor pressure, inorganic-based explosive signatures including ammonium nitrate, chlorate, perchlorate, sugar, and the constituents contained within black powder are reported using laser electrospray mass spectrometry. The ambient pressure mass spectrometry technique combining nonresonant, femtosecond laser vaporization with electrospray postionization reveale...

Symptomatic benign prostatic hyperplasia (BPH) is managed medically worldwide, but transurethral resection of prostate (TURP) is the gold standard in refractory cases. Holmium laser enucleation of prostate (HoLEP), laser vaporization are other options which are widely practiced. However in larger glands which are more than 80 g, open adenomectomy is still practiced. Laparoscopic adenomectomy is...

Laser ablation is used in a growing number of applications in various areas including medicine, archaeology, chemistry, environmental and materials sciences. In this work the heat transfer and phase change phenomena during nanosecond laser ablation of a copper (Cu) target in a helium (He) background gas at atmospheric pressure are presented. An enthalpy model is outlined, which accounts for hea...

Recent innovations in thulium laser techniques have allowed application in the treatment of bladder cancer. Laser en bloc resection of bladder cancer is a transurethral procedure that may offer an alternative to the conventional transurethral resection procedure. We conducted a review of basic thulium laser physics and laser en bloc resection procedures and summarized the current clinical liter...

In the era of therapeutic endoscopy, a new device for precise cutting and simultaneous hemostasis is required. Laser technology allows immediate vaporization of tissue. The thulium laser is a new type of surgical laser. It emits a continuous 2-μm wavelength delivered through a thin, flexible laser fiber. Its penetration depth is approximately 0.25 mm, which is suitable for tissue resection with...
