Abstract
Mushroom poisoning occurs frequently after the ingestion of toxic wild mushrooms misidentified as edible species. The goal of this study is to develop a mass spectrometric platform to bypass the need for morphological recognition of poisonous mushrooms by experts and rapidly identify the toxins in the mushrooms for emergency care. Trace mushroom toxins were collected by penetrating and removing the mushrooms surface for 3 mm with a direct electrospray probe (DEP). The analytes on the DEP were then dissolved in the solution (70% isopropanol containing 0.1% acetic acid) flowing out of a solvent reservoir on the DEP. Electrospray ionization was induced from the sample solution as a high electric field was generated between the DEP and MS inlet. The obtaining mass spectrometric results were further analyzed with principal component analysis (PCA) to classify mushroom toxins. The mass spectrometric platform for detecting mushroom toxins was assessed for its sensitivity, precision, and efficiency by determining its limit-of-detection (LOD), repeatability, and turnaround time, respectively. As a result, the LODs of the mushroom toxins in pure methanol and spiked in human vomitus by DEP/MS were within 0.001-0.5 ng/μL and 0.01-1 ng/μL, respectively. Linear responses of the mushroom toxins in pure methanol with concentrations between 0.01 and 5 ng/μL (R2 between 0.9922 and 0.998) were obtained. The repeatability of the approach (n = 10) was shown in the low relative standard deviation value (<15%) from ten repeat analysis of mushroom toxins standard solution. The corresponding toxic compounds were identified through matching of the obtained mass spectrometric data with those provided by its companion database library of mushroom toxins. Since no time-consuming pretreatment of the samples is required, identification of mushroom toxins with DEP/MS was complete within 1 min. This will be helpful for the emergency physicians to make correct clinical judgment and prescribe appropriate medical treatment in a timely manner.

Abstract
In the previous work, sheath-flow probe electrospray ionization (sfPESI) equipped with a touch sensor was developed for conducting samples. In this work, a capacitiance-sensitive touch sensor that can be applicable to samples prepared in a nonconducting plastic multiwell plate was developed. The radiofrequency with 5 kHz and 4.5 Vpp was applied to the metal substrate on which the plastic plate was placed. The probe tip stopped at the position where it touched the surface of the liquid solution prepared in the plastic multiwell plate by detecting the displacement current flowing through the capacitance of the circuit. By coupling a nondisposable sfPESI probe with a table-top 3-axis robot, consecutive analysis of peptides, proteins, drugs, and real samples was performed. The carry-over by the consecutive analyses was suppressed to minimal by cleansing the probe tip using the solvent of water/methanol/acetonitrile (1/1/1).
