  • amphiphilic functionalized Acupuncture Needle as sers sensor for in situ multiphase detection
    Analytical Chemistry, 2018
    Co-Authors: Binbin Zhou, Xiaomin Cao, Xianghu Tang, Liangbao Yang, Mei Mao, Dongyue Lin, Jinhuai Liu

    Abstract:

    Surface enhanced Raman spectroscopy (SERS) is a powerful spectroscopic technique with unique vibrational fingerprints, making it an ideal candidate for in situ multiphase detection. However, it is a great challenge to determine how to guide the SERS sensor to target molecules of interest in multiphase heterogeneous samples with minimal disturbance. Here, we present a portable ultrasensitive and highly repeatable SERS sensor for in situ multiphase detection. The sensor is composed of commercial Ag Acupuncture Needle and PVP-Au nanoparticles (Au NPs). The PVP on the Au NPs can adsorb and induce the Au NPs into a highly uniform array on the surface of the Ag Needle because of its adhesiveness and steric nature. The Au NPs-Ag Needle system (Au-AgN) holds a huge SERS effect, which is enabled by the multiple plasmonic couplings from particle–film and interparticle. The PVP, as the amphiphilic polymer, promotes the target molecules to adsorb on surface of the Au-AgN whether in the oil phase or in the water phase…

  • functionalized Acupuncture Needle as surface enhanced resonance raman spectroscopy sensor for rapid and sensitive detection of dopamine in serum and cerebrospinal fluid
    Chemistry: A European Journal, 2017
    Co-Authors: Binbin Zhou, Xiaomin Cao, Xianghu Tang, Liangbao Yang, Jinhuai Liu

    Abstract:

    It is a challenge to develop a robust sensor for simple, rapid operation and sensitive detection of neurotransmitters in complex specimens. Herein, ferric citrate functionalized gold nanoparticles (CA-FeIII /Au NPs) are utilized to develop a facile sensor based on surface-enhanced resonance Raman spectroscopy (SERRS) for sensitive detection of dopamine (DA). The sensor is prepared by decorating the Acupuncture Needle with Au NPs, which enables sufficient surface-enhanced Raman spectroscopy enhancement. The CA-FeIII structure is highly sensitive and selective for DA due to the formation of the CA-FeIII -DA resonant structure; this indicates the advantages of capturing, carrying, and separating DA molecules from complicated samples in a simple operation. Furthermore, the practical application of the fabricated sensor is validated by the detection of DA in pretreated serum and cerebrospinal fluid of Acupuncture-treated mice with detection limits of 0.1 and 2.5 nm DA, respectively. The developed active Acupuncture Needle sensor has potential benefits for sensitive detection and qualitative identification of DA molecules from biological samples.

  • Decoding spatial location of perceived pain to Acupuncture Needle using multivoxel pattern analysis

    Abstract:

    Abstract
    The present study applied multivoxel pattern analysis to decode spatial discrimination in pain perception to Acupuncture Needle from brain functional magnetic resonance image. Fourteen participants were stimulated by Acupuncture Needles at two adjacent body parts on their left forearm (PC6 vs. HT7). We trained support vector machines on the spatial information from the whole-brain functional magnetic resonance imaging data and projected the support vector machine weight to the brain image space to represent the effect of each voxel on the classifier output. Using region-of-interest masks in individual brains, we trained and tested a linear support vector machine classifier on the accuracy of spatial discrimination in trial-wise functional magnetic resonance imaging data. A classical univariate general linear model analysis testing for differences between the two different locations did not reveal any significant differences. Multivoxel pattern analysis revealed that the brain regions for the prediction of sensory discrimination in pain perceptions to two different points were in the primary somatosensory cortex, primary motor cortex, and supramarginal gyrus, anterior and posterior insula, anterior and posterior cingulate cortex, ventromedial prefrontal cortex, and inferior parietal lobule. Our findings suggest that spatial localizations of pain perceptions to Acupuncture Needle can be predicted by the neural response patterns in the somatosensory areas and the frontoparietal areas. C.

  • Sensorimotor Learning of Acupuncture Needle Manipulation Using Visual Feedback
    PLOS ONE, 2015
    Co-Authors: Won Mo Jung, Hi-joon Park, Jinwoong Lim, In-seon Lee, Christian Wallraven, Younbyoung Chae

    Abstract:

    Objective
    Humans can acquire a wide variety of motor skills using sensory feedback pertaining to discrepancies between intended and actual movements. Acupuncture Needle manipulation involves sophisticated hand movements and represents a fundamental skill for acupuncturists. We investigated whether untrained students could improve their motor performance during Acupuncture Needle manipulation using visual feedback (VF).

    Methods
    Twenty-one untrained medical students were included, randomly divided into concurrent (n = 10) and post-trial (n = 11) VF groups. Both groups were trained in simple lift/thrusting techniques during session 1, and in complicated lift/thrusting techniques in session 2 (eight training trials per session). We compared the motion patterns and error magnitudes of pre- and post-training tests.

    Results
    During motion pattern analysis, both the concurrent and post-trial VF groups exhibited greater improvements in motion patterns during the complicated lifting/thrusting session. In the magnitude error analysis, both groups also exhibited reduced error magnitudes during the simple lifting/thrusting session. For the training period, the concurrent VF group exhibited reduced error magnitudes across all training trials, whereas the post-trial VF group was characterized by greater error magnitudes during initial trials, which gradually reduced during later trials.

    Conclusions
    Our findings suggest that novices can improve the sophisticated hand movements required for Acupuncture Needle manipulation using sensorimotor learning with VF. Use of two types of VF can be beneficial for untrained students in terms of learning how to manipulate Acupuncture Needles, using either automatic or cognitive processes.
